실험 절차
A solution of methanesulfonic acid (88 mg) in methanol (100 ml) was added to (2β,3α,5α)-3-hydroxy-2-(2,2-dimethyl-4-morpholinyl)-21-thiocyanatopregnan-20-one (445 mg) and the solvent was removed from the resulting solution to give (2β,3α,5α)-3-hydroxy-2-(2,2-dimethyl-4-morpholinyl)-21-thiocyanatopregnan-20-one methanesulfonate (1:1) salt (432 mg). [α]D +100.8° (c 0.4).
