PROCEDURE

实验过程

A solution of 23.1 g of 11β-fluoro-7α-(5-tert-butyl-dimethylsilyloxypentyl)oestr-4-ene-3,17-dione in 115 ml of THF and 64 ml of water are stirred at 50° C. for 2.5 h with 128 ml of glacial acetic acid. The reaction mixture is concentrated in vacuo, taken up in ethyl acetate, and the solution is washed with water and dried. 20.4 g of 11β-fluoro-7α-(5-hydroxypentyl)oestr-4-ene-3,17-dione are obtained as a foam.
