Abstract

A process for the preparation of racemic 13β-ethyl-3-methoxy-8,14-seco-gona-1,3,5 (10), 8-tetraene-17β-ol-14-one, in which one of the oxo groups of 13-ethyl-3-methoxy-8,14-seco-gona-1,3,5 (10), 9-tetraene-14,17-dione are reduced with sodium borohydride in the presence of a hydroxide and/or an alkali metal alcoholate, the obtained diastereoisomer mixture, which contains 13β-ethyl-3-methoxy-8,14-seco-gona-1,3,5 (10), 9-tetraene-17β-ol-14-one Racemic as the main component, it is reacted with an organic acid, and the 13β-ethyl-3-methoxy-8,14-seco-gona-1,3,5 (10), 8-tetraene is separated from the reaction mixture. -17β-ol-14-one.
