Versuchsvorschrift

A solution of methanesulfonic acid (17.7 mg) in methanol (10 ml) was added to a solution of (2β,3α,5α)-3,21-dihydroxy-2-(2,2-dimethyl-4-morpholinyl)pregnane-11,20-dione (85 ml) in methanol (10 ml). The solvent was removed under reduced pressure to give (2β,3α,5α)-3,21-dihydroxy-2-(2,2-dimethyl-4-morpholinyl)pregnane-11,20-dione methanesulfonate (1:1) salt (103 mg). δ (CDCl3) 0.63 (s,3H), 1.07 (s,3H), 1.34 (s,3H), 1.52 (s,3H) and 4.18 (s,2H).
