PROCESS FOR PREPARING ESTROGEN ESTROGEN-ANTAGONISTIC 11ß-FLUORO-17α-ALKYLESTRA-1,3,5(10)-TRIENE-3,17--DIOLS HAVING A 7α-(ξ-ALKYLAMINO-ω-PERFLUOROALKYL)ALKYL SIDE CHAIN AND α-ALKYL(AMINO)-ω-(PERFLUORO(ALKYL)ALKANES AND PROCESSES FOR THEIR PREPARATION

摘要

The present invention relates to a new process for preparing estrogen-antagonistic 11ß-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.
