PROCEDURE

实验过程

A mixture of 17β-hydroxy-1α-methyl-4-androsten-19-one, trimethylchlorosilane and pyridine is refluxed in benzene for a period of about 18 hours. The suspension is filtered and the benzene removed under vacuum. The resulting oil is eluted from a silica gel chromatograph with benzene and crystallized from hexane to yield 1α-methyl-17β-trimethylsiloxy-4-androsten-19-one.
