実験手順
A solution of 6.00 g of 3β-acetoxy-14β-ethoxymethoxyandrosta-5,15-dien-17-one and 30 ml of 2 N aq. sodium hydroxide in 120 ml of methanol was kept at room temperature for 24 hrs. The mixture was then diluted with water and extracted with dichloromethane. The organic phase was dried over sodium sulfate and evaporated to dryness to give 4.90 g of the title compound (II-a) as a white solid
