Reaction Steps
Palladium on charcoal (5%, 110 mg.) is added to a solution of 2-ethylidene-17β-methoxy-5α-androstan-3-one (Preparation 1, 1.5 g.) and shaken under hydrogen. The catalyst is removed by filtration and the filtrate is concentrated to dryness and chromatographed to give 2β-ethyl-17β-methoxy-5α-androstan-3-one.
