PROCESS FOR PREPARING ESTROGEN-ANTAGONISTIC 11 BETA-FLUORO-17 ALPHA-ALKYLESTRA-1,3,5(10)-TRIENE-3,17-DIOLS HAVING A 7 ALPHA-(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 11 β-fluoro-17α-alkylestra-1,3,5(10)-triene-3,17-diols of the general formula (I) having a 7α-(ξ-alkylamino-ω-perfluoroalkyl)alkyl side chain and to α-alkyl(amino)-ω-perfluoro(alkyl)alkanes of the general formula (II), to processes for their preparation and to the intermediates required for this purpose.
