    This invention relates to a method for the preparation of platinum CI-diamino plexes for complexes exhibiting antitumor activity. A known method for the preparation of the compound of Ni-Shatin (1U) -diamine complexes exhibits antitumor activity, which consists in that the compound. platinum of the formula P.UCf where L 2,2-dimethyl-1,3-diaminopropane (DMDAR) or Y, H-2,2-tetramethyl-1,3 diaminopropane (TMDAR) is treated with 30.% - g and then 2M ticl at boiling of the reaction mass with the following release of the desired product Clj. The disadvantage of this method is to obtain whole products with low antitumor activity. The purpose of the invention is a method of obtaining platinum (IV 1-diamine complexes / exhibiting high antitum cholangus activity with low toxicity for the kidneys). The goal is achieved by using the (IV) diamine complexes of the general formula V 2- l "H ,, f X Bg where R and R together with C are € 4- C cycloalkyl or R and R2 are lower alkyl, except when R-- is methyl, X and Y are C1 O or X is an anionic group, such as a halogen or hydroxy group, the cis-diol-2,2-dimethyl alkyl-1,3-diamino-alkane pt (i) is subjected to oxidation with 30% hydrogen peroxide or. with chlorine at 70-100s followed by isolation of the desired product or, if necessary, the compound of formula {1), where Y is OH, is transferred to the compound of formula {1), where Y is C1, by treatment with concentrated hydrochloric acid at 95 110 ° C.
