Procedure
A solution of 3β,19-dihydroxyandrost-5-en-17-one diacetate in methanol is hydrogenated with a 10% Palladium-on-charcoal catalyst at atmospheric pressure for 8 hours. The catalyst is removed by filtration and the filtrate concentrated to a small volume, cooled, and filtered to yield the desired 3β,19-dihydroxy-5α-androstan-17-one diacetate. Recrystallization from hexane results in pure material.
