PROCEDURE

实验过程

7.4 g of 7α-(5-acetoxypentyl)-11β-fluoro-3-(tetrahydropyran-2-yloxy)-estra-1,3,5(10)-trien-17-one in 370 ml of methanol and 37 ml of water is stirred at room temperature with 1.8 g of potassium carbonate. After 3 hours, the reaction mixture is added to ice water. The precipitated product is suctioned off, dissolved in ethyl acetate, washed neutral with water, dried and concentrated by evaporation in a vacuum. 7.0 g of 11β-fluoro-7α-(5-hydroxypentyl)-3-(tetrahydropyran-2-yloxy)-estra-1,3,5(10)-trien-17-one is obtained as foam.
