Process for preparing Estrogen-antagonistic 11 beta-Fluoro-17alpha-alkylestra-1,3,5(10)-triene-3,17-diols having a 7alpha-(xi-Alkylamino-omega-perfluoroalkyl)alkyl side chain and alpha-Alkyl(amino)-omega-perfluoro(alkyl)alkanes and Processes for their Preparation

摘要

The present invention relates to a new process for preparing estrogen-antagonistic 11beta-fluoro-17alpha-alkylestra-1,3,5(10)-triene-3,17-diols of the general formula I having a 7alpha-(xi-alkylamino-omega-perfluoroalkyl)alkyl side chain and to alpha-alkyl(amino)-omega-perfluoro(alkyl)alkanes of the general formula II, to processes for their preparation and to the intermediates required for this purpose.
