PROCEDURE
实验过程
A mixture of 17β,19-dihydroxy-1α-methyl-5α-androstan-3-one, trimethylchlorosilane and pyridine in benzene is heated to its reflux temperature for a period of about 14 hours. The reaction mixture is vacuum filtered, the organic layer is washed with water, dried over magnesium sulfate and concentrated in vacuum. Crystallization of the residue from hexane yields 1α-methyl-17β,19-di(trimethylsiloxy)-5α-androstan-3-one.
