A solution of 3α-hydroxy-17β-(2'-morpholinoethoxycarbonyl)-5β-androstan-11-one (112 mg., 0.25 mmole) in ethanol (2 ml.) was treated with 0.01 N aqueous citric acid (2.5 ml; 0.25 mmole) and the resulting mixture was evaporated to dryness. The residue was treated with water (1.1 ml) to give an aqueous solution of the title compound (10% with respect to free steroidal base).
