FIELD: chemistry.
SUBSTANCE: present invention pertains to the method of producing compounds with formula I and to their pharmaceutical salts. In formulae I, II, IV, V: R1 or R2 represent H, -(CH2)t(5-member heterocyclic compound), where t equals 4 and where the heterocyclic compound contains one nitrogen atom as the heteroatom, R3 is -(CH2)t(C6-C10aryl), where t equals 1. The given R3 groups are optionally substituted with 3 R4 groups. Each R4 is independently chosen from halogen. R8 is C1-C10alkyl, R9 is C1-C10alkyl, and n equals 2.
EFFECT: treatment of hyper-proliferative diseases using new intermediate compounds with formulae II, IV, V.
