実験手順
At room temperature, 0.43 g (1.27 mmol) of 9α-cyano-3-hydroxy-estra-1,3,5(10)-trien-16α-yl-acetate is stirred for 2 hours with 1.0 g (7.24 mmol) of potassium carbonate in 40 ml of methanol (1% water). Then, the methanol is distilled off in a vacuum, and the organic residue is dissolved in methylene chloride. The organic phase is washed with water and concentrated by evaporation. 3.5 g (93%) of 9α-cyano-estra-1,3,5(10)-triene-3,16α-diol is obtained.
