Reaction Steps
A solution of 7α-methyl-5-androstene-3,17,19-trione in ethanol is hydrogenated with 5% palladium on charcoal. The catalyst is removed by filtration and the resulting solution evaporated to dryness. Crystallization of the residue from a pentane-ether solution results in the preparation of 7α-methyl-5α-androstane-3,17,19-trione.
