Reaction Steps

A suspension of 2.0 g. of 16-ethylidene-3-methoxy-1,3,5(10)-estratrien-17-one in 80 ml. of ethanol is combined with 200 mg. of 10% palladium-charcoal and hydrogenated for 60 minutes at room temperature under normal pressure. After removing the catalyst by filtration and concentration of the reaction product, 2.0 g. of 16β-ethyl-3-methoxy-1,3,5(10)-estratrien-17-one is obtained, m.p. 93°-94° C.
