The method of obtaining 1,1,2-triphenyl propene derivatives as a mixture of isomers or trans-isomer, or their salts. This invention relates to a process for the preparation of new 1,1,1triphenyl propene derivatives having headlamp acological activity. It is known that some derivatives of triphenylalkenes containing the main substituents at the aromatic ring possess anti-estrogenic activity. Two of the most important representatives of this group of compounds are clomiphene (2-diethylaminoethi-2-phenyl -1,2-diphenyl-2-chloroethylene and tamoxifenG (g) -1 - 4- (2-dimethylamino-1-oxy) -phenyl -1, 2-diphenyl-1-butene Q. Although both compounds have anti-estrogenic properties, the first is taken to cause ovulation, and tamoxifen, on the contrary, is primarily treatment of breast tumors. With prolonged use of both compounds, undesirable side effects, namely deterioration of vision, are observed. The purpose of the invention is a method of producing new compounds with anti-estrogenic activity, which in their action are superior to known derivatives, have a specific effect and have very little side effects. . This goal is achieved by the preparation of 1,1,2-triphenyl propene derivatives of the formula CF, -C C- / Vo-CHo-CHo-1) -0-CH2-CH2-NC where X and Y may be the same or different and each means unsubstituted or substituted in the P-position of the Institute of Oxy-, methoxy-methoxy, C.-alkoxy- or benzo-hydroxy, phenyl; R and R-J hydrogen, C |, -alkyl or Ci A-OKCHanKHn or together with the nitrogen atom form a morpholine group, as a mixture of isomers or trans-isomer or their salts. The method of obtaining compounds of formula I is based on the known reaction of the interaction of mixed esters of halides with alkali metal alkoxides (Wilson reaction) 2 and consists in the compound of formula II where X and Y have the indicated values, with the exception of hydroxy groups, are reacted with an alkali metal alkali metal of the formula HO-CH2-CH2-1 where M is an alkali metal; Rj and R have the indicated meanings, in a medium of a bipolar aprotic solvent, such as dimethylacetamide, at 140-180 ° C, and, if necessary, followed by cleavage, of methoxy methoxy or benzyloxy groups under acid conditions, the target product is given in the form of a mixture of isomers or trans isomer in free form or in salt form.

eleven
As can be seen from the table. 1, the anti-estrogenic effect of some compounds is at the level of the known anti-estrogenic agents, clomiphene and tamoxifen.
The hormone-dependent tumor effect of the compounds is determined by the example of 7,12-dimesh1-benz (a) anthracene (DMBA) induced breast carcinoma. The treatment begins with a tumor weight of 500 mg and is treated three times a week for a month at a dose of
1433212
20 mg / kg orally. Measurement of the tumor and observation of the animals is continued for 2 months after the end of the treatment period.
For the evaluation of the effect, the relative efficiency index is introduced: this value is determined on the basis of counting the final baked or temporarily baked, animals with long or short remission.
