    IN THE MATTER OF an Australian Application corresponding to PCT Application PCT/EP2004/013931 RWS Group Ltd, of Europa House, Marsham Way, Gerrards Cross, Buckinghamshire, England, hereby solemnly and sincerely declares that, to the best of its knowledge and belief, the following document, prepared by one of its translators competent in the art and conversant with the English and German languages, is a true and correct translation of the PCT Application filed under No. PCT/EP2004/013931. Date: 31 May 2006 S.ANTHONY Director For and on behalf of RWS Group Ltd WO 2005/056556 - 1 - PCT/EP2004/013931 Pyrazolopyrimidines The present invention relates to pyrazolopyrimidines, to a plurality of processes for their preparation and to their use for controlling unwanted microorganisms. It is already known that certain pyrazolopyrimidines have fungicidal properties (compare DE-A 5 3 130 633 or FR-A 2 794 745). However, since the ecological and economical demands made on modem fungicides are increasing constantly, for example with respect to activity spectrum, toxicity, selectivity, application rate, formation of residues and favorable manufacture, and there can furthermore be problems, for example, with resistance, there is a constant need to develop novel fungicides which, at least in 10 some areas, have advantages over those of the prior art. This invention now provides novel pyrazolopyrimidines of the formula 1 2 1-1 N e R - -R N R NN R6 N %R3 R4 in which
    R
    ' represents hydrogen, optionally substituted alkyl, optionally substituted alkenyl, 15 optionally substituted alkynyl, optionally substituted cycloalkyl or represents optionally substituted heterocyclyl,
    R
    2 represents hydrogen or alkyl, or R' and R 2 together with the nitrogen atom to which they are attached represent an optionally substituted heterocyclic ring, 20 R 3 represents hydrogen, halogen, optionally substituted alkyl or optionally substituted cycloalkyl, -X
    R
    4 represents a radical of the formula =X, in which
    NH
    2 X represents an oxygen atom, an HN group, an HO-N group or Z-O-N=, in which -2 Z represents optionally substituted alkyl or aralkyl, or
    R
    4 represents a radical of the formula -C
    =
    N-R , in which
    R
    7
    R
    7 represents hydrogen or alkyl and 5 R' represents optionally substituted alkyl, optionally substituted phenyl or represents optionally substituted phenylamino,
    R
    5 represents halogen, optionally substituted alkoxy, optionally substituted alkylthio, optionally substituted alkylsulfinyl or represents optionally substituted alkylsulfonyl, and
    R
    6 represents optionally substituted aryl. 10 Furthermore, it has been found that pyrazolopyrimidines of the formula (I) are obtained when a) cyano compounds of the formula 1 2 R N.R RN N R N R 3 (] CN in which R', R 2 , R 3 , R 5 and R 6 are as defined above 15 are either a) reacted with acids and water, if appropriate in the presence of a diluent, B) reacted with hydroxylamine or a hydroxylammonium salt in the presence of a diluent and, if appropriate, in the presence of a catalyst, or -3 y) reacted with ammonium chloride in the presence of a base and in the presence of a diluent, or b) carbonyl compounds of the formula 1 2 NR
    R
    6 NN /( NN R N N 7 5 R 5 in which
    R
    I
    , R 2 , R 3 , R 5 , R 6 and R 7 are as defined above are reacted with amino compounds of the formula
    H
    2
    N-R
    8 (IV) 10 in which
    R
    8 is as defined above, in the presence of a diluent and, if appropriate, in the presence of a catalyst, where the amino compounds of the formula (IV) may also be employed in the form of their acid addition salts. Finally, it has been found that the pyrazolopyrimidines of the formula (I) are highly suitable for 15 controlling unwanted microorganisms. In particular, they have strong fungicidal activity and can be used both in crop protection and in the protection of materials. Depending on the substitution pattern, the compounds according to the invention can, if appropriate, be present as mixtures of different possible isomeric forms, in particular of stereoisomers, such as E and Z, threo and erythro and also optical isomers, and, if appropriate, also 20 in the form of tautomers. If R 6 is substituted by different substituents on the two atoms adjacent to the point of attachment, the compounds in question may be present in a particular stereoisomeric form, i.e. as atropisomers.

A mixture with other known active compounds, such as herbicides, or with fertilizers and growth regulators, safeners and/or semiochemicals is also possible.
    -37 In addition, the compounds of the formula (I) according to the invention also have very good antimycotic activity. They have a very broad antimycotic activity spectrum in particular against dermatophytes and yeasts, molds and diphasic fungi (for example against Candida species such as Candida albicans, Candida glabrata) and Epidermophyton floccosum, Aspergillus species such as 5 Aspergillus niger and Aspergillus fumigatus, Trichophyton species such as Trichophyton mentagrophytes, Microsporon species such as Microsporon canis and audouinii. The list of these fungi does by no means limit the mycotic spectrum which can be covered, but is only for illustration. The active compounds can be used as such, in the form of their formulations or the use forms 10 prepared therefrom, such as ready-to-use solutions, suspensions, wettable powders, pastes, soluble powders, dusts and granules. Application is carried out in a customary manner, for example by watering, spraying, atomizing, broadcasting, dusting, foaming, spreading, etc. It is furthermore possible to apply the active compounds by the ultra-low volume method, or to inject the active compound preparation or the active compound itself into the soil. It is also possible to treat the 15 seeds of the plants. When using the active compounds according to the invention as fungicides, the application rates can be varied within a relatively wide range, depending on the kind of application. For the treatment of parts of plants, the active compound application rates are generally between 0.1 and 10 000 g/ha, preferably between 10 and 1000 g/ha. For seed dressing, the active compound 20 application rates are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 10 g per kilogram of seed. For the treatment of the soil, the active compound application rates are generally between 0.1 and 10 000 g/ha, preferably between 1 and 5000 g/ha. As already mentioned above, it is possible to treat all plants and their parts according to the invention. In a preferred embodiment, wild plant species and plant cultivars, or those obtained by 25 conventional biological breeding, such as crossing or protoplast fusion, and parts thereof, are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof, are treated. The term "parts" or "parts of plants" or "plant parts" has been explained above. 30 Particularly preferably, plants of the plant cultivars which are in each case commercially available or in use are treated according to the invention. Plant cultivars are to be understood as meaning plants having new properties ("traits") and which have been obtained by conventional breeding, by mutagenesis or by recombinant DNA techniques. They can be cultivars, varieties, bio- or genotypes.
    -38 Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive ("synergistic") effects. Thus, for example, reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the substances and 5 compositions which can be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products are possible which exceed the effects 10 which were actually to be expected. The transgenic plants or plant cultivars (i.e. those obtained by genetic engineering) which are preferably to be treated according to the invention include all plants which, in the genetic modification, received genetic material which imparted particularly advantageous useful properties ("traits") to these plants. Examples of such traits are better plant growth, increased tolerance to 15 high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products. Further and particularly emphasized examples of such properties are a better defense of the plants against animal and microbial pests, such as against 20 insects, mites, phytopathogenic fungi, bacteria and/or viruses, and also increased tolerance of the plants to certain herbicidally active compounds. Examples of transgenic plants which may be mentioned are the important crop plants, such as cereals (wheat, rice), corn, soy beans, potatoes, cotton, tobacco, oilseed rape and also fruit plants (with the fruits apples, pears, citrus fruits and grapes), and particular emphasis is given to corn, soy beans, potatoes, cotton, tobacco and oilseed 25 rape. Traits that are particularly emphasized are increased defense of the plants against insects, arachnids, nematodes and slugs and snails by toxins formed in the plants, in particular those formed in the plants by the genetic material from Bacillus thuringiensis (for example by the genes CryIA(a), CryIA(b), CryIA(c), CryllA, CryIIIA, CrylIB2, Cry9c, Cry2Ab, Cry3Bb and CryIF and also combinations thereof) (hereinbelow referred to as "Bt plants"). Traits that are also particularly 30 emphasized are the increased defense of the plants against fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and correspondingly expressed proteins and toxins. Traits that are furthermore particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulfonylureas, glyphosate or phosphinotricin (for example the "PAT" gene). The 35 genes which impart the desired traits in question can also be present in combination with one another in the transgenic plants. Examples of "Bt plants" which may be mentioned are corn -39 varieties, cotton varieties, soy bean varieties and potato varieties which are sold under the trade names YIELD GARD® (for example corn, cotton, soy beans), KnockOutv (for example corn), StarLink® (for example corn), Bollgard® (cotton), Nucoton® (cotton) and NewLeaf® (potato). Examples of herbicide-tolerant plants which may be mentioned are corn varieties, cotton varieties 5 and soy bean varieties which are sold under the trade names Roundup Ready® (tolerance to glyphosate, for example corn, cotton, soy bean), Liberty Link® (tolerance to phosphinotricin, for example oilseed rape), IMI® (tolerance to imidazolinones) and STS® (tolerance to sulfonylureas, for example corn). Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned also include the varieties sold under the name Clearfield® (for 10 example corn). Of course, these statements also apply to plant cultivars which have these genetic traits or genetic traits still to be developed, and which will be developed and/or marketed in the future. The plants listed can be treated according to the invention in a particularly advantageous manner with the compounds of the general formula (I) or the active compound mixtures according to the 15 invention. The preferred ranges stated above for the active compounds or mixtures also apply to the treatment of these plants. Particular emphasis is given to the treatment of plants with the compounds or mixtures specifically mentioned in the present text. The compounds of the formula (I) according to the invention are furthermore suitable for suppressing the growth of tumour cells in humans and mammals. This is based on an interaction of 20 the compounds according to the invention with tubulin and microtubuli and by promoting microtubuli polymerization. For this purpose, it is possible to administer an effective amount of one or more compounds of the formula (I) or pharmaceutically acceptable salts thereof. The preparation and the use of the active compounds according to the invention is illustrated in the 25 examples below.

After the addition has ended, the reaction mixture is stirred at room temperature for 3 hours and then stirred into a mixture of water and hydrochloric acid. The resulting solid product is filtered off with suction, washed repeatedly with water and dried. This gives 10.8 g (90.79% of theory) of 3-cyano-5-chloro-6-(2-chloro-6 10 fluorophenyl)-7-(3,3-dimethylbut-2-ylamino)pyrazolo[1,5-a]pyrimidine. HPLC: logP = 4.59.

The methanol formed during the reaction is continuously distilled off. The reaction mixture is then cooled to room temperature. At 95 0 C and 1 mbar, volatile components are distilled off. The residue obtained is 6-(2-chloro-4-fluorophenyl)-5,7-dihydroxy pyrazolo[1,5-a]pyrimidine-3-carbonitrile in the form of a crude product which is used without 10 additional purification for further synthesis.
