실험 절차
A solution of methanesulfonic acid (186 mg) in ethanol (2 ml) was added to a suspension of (2β,3α,5α,17β)-3-hydroxy-2-(2,2-dimethyl-4-morpholinyl)androstane-17-carbonitrile (800 mg) in ethanol (8 ml) and the mixture was stirred for 5 min. Removal of the solvent under reduced pressure afforded a solid which was precipitated from ethanol-diethyl ether to give (2β,3α,5α,17β)-3-hydroxy-2-(2,2-dimethyl-4-morpholinyl)androstane-17-carbonitrile methanesulfonate (1:1) salt (890 mg).
