PROCEDURE
实验过程
7.8 g of 11β-fluoro-estr-4-ene-3,17-dione (A′) was stirred in 40 ml of 2,2-dimethoxypropane with 780 mg of pyridinium-toluene-4-sulfonate for 5 hours at 80° C. Then, 1.5 ml of triethylamine was added. Then, it was diluted with ethyl acetate and washed with saturated sodium chloride solution. After crystallization from methanol, 5.3 g of 11β-fluoro-3-methoxy-estra-3,5-dien-17-one (A″) with a melting point of 173° C. was obtained.
