PROCEDURE
实验过程
Stir dl-13-ethyl-3-methoxy-17α-ethynyl-17-hydroxy-6-methylgona-2,5(10)-diene (3.5 g) in methanol (90 cc) containing hydrochloric acid (60 cc) and water (4.0 ml) under nitrogen for one hour. Isolate the crude product, chromatograph on Florex (150 g) and recrystallize from ethyl acetate-hexane to obtain the title compound (0.60 g), m.p. 148°-151°, λ max. CHCl3 2.55 μ, 3.05 μ, 6.01 μ; λ max. EtOH 240 mμ (ε15,000).
