실험 절차

Dissolve dl-3-methoxyestra-2,5(10)-dien-17β-ol (0.84 g) in methanol (18 ml) containing concentrated hydrochloric acid (1.2 ml) and water (0.8 ml) and allow the mixture to stand at room temperature for 15 hours. Add water and extract the mixture with ether. Wash, dry and evaporate the ethanol solution and dissolve the residue in a little benzene. Filter through a column of alumina (25 g) with benzene-ether (7.3). Evaporate the eluates and recrystallize the residue from etherhexane to obtain the title compound (372 mg), m.p. 123°-124.5° or in an alternate form, m.p. 131°-132°; ultraviolet absorption maximum at 241 mμ (ε16,600); infrared absorption peaks at 6μ, 7.9 μ, 9.4 μ.
