PROCEDURE

实验过程

A solution of citric acid (368 mg) in methanol (4 ml) was added to a solution of (2β,3α,5α)-3-hydroxy-2-(2,2-dimethyl-4-morpholinyl)pregnane-11,20-dione of Example 1 (854 mg) in methanol (6 ml). The solvent was removed under reduced pressure to give (2β,3α,5α)-3-hydroxy-2-(2,2-dimethyl-4-morpholinyl)-pregnane-11,20-dione 2-hydroxy-1,2,3-propanetricarboxylate (1:1) salt (1.22 g). [α]D +96.6° (c 1.03).
