    摘要: The present invention relates to a process for the synthesis of the known 17-acetoxy-11-β-[4-(dimethyl amino)-phenyl]-21-methoxy-19-norpregna-4,9-dien-3,20-dione (further on CDB-4124) of formula (I) from 3,3-[1,2-ethandiyl-bis(oxy)]-oestr-5(10),9(11)-dien-17-one of formula (II). Compound CDB-4124 belongs to the group of anti-hormones. The process has the following steps: i) formation of an epoxide; ii) addition of hydrogen cyanide; iii) silylation of a hydroxyl group; iv) reaction with 4-(dimethylamino)-phenyl magnesium bromide Grignard reagent in the presence of CuCl (Teutsch reaction); v) silylation of a hydroxyl group with trimethyl chlorosilane; vi) reaction with diisobutyl aluminum hydride and after addition of acid to the reaction mixture; vii) methoxy-methylation with methoxy-methyl Grignard reagent formed in situ, while hydrolyzing the trimethylsilyl protective groups; viii) oxidation of a hydroxyl group with dicyclohexyl carbodiimide in the presence of dimethyl sulfoxide and a strong organic acid (Swern oxidation), and in given case after purification by chromatography; ix) acetylation of a hydroxyl group with acetic anhydride in the presence of perchloric acid, and in given case, purification by chromatography. The invention also relates to new intermediates of the process.
