PROCEDURE
实验过程
Raney nickel is added to a solution of the above 17β,19-dihydroxy-1α-methyl-4-androsten-3-one 3-ethylenethioketal in methanol and the resulting suspension is refluxed for about 4 hours with rapid stirring. The suspension is cooled, filtered and the solvent evaporated. The residue is chromatographed on silica gel and eluted with methylenechloride. Recrystallization from acetone-hexane yields 1α-methyl-4-androstene-17β,19-diol.
