PROCEDURE

实验过程

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