Procedure
Birch reduction of the (14β,17α)-3-methoxyestra-1,3,5(10)-triene-17-methanol derivatives thus obtained [Caine, D. in Org. Reactions 23, p. 1, Wiley, New York, 1976] and hydrolysis of the resulting (14β,17α)-3-methoxyestra-2,5(10)-diene-17-methanol derivative then provides a (14β,17α)-17-(hydroxymethyl)estr-4-en-3-one derivative of the invention.
