Procedure

A solution of 300 mg of 11β-fluoro-7α-{5-[(2S)-2-(4,4,5,5,5-pentafluoropentylthiomethyl)-pyrrolidin-1-yl]-pentyl}-estra-1,3,5(10)-triene-3,17β-diol in 4.3 ml of methanol and 2.1 ml of water is stirred with 131 mg of sodium periodate for 4 hours at room temperature. Then, it is added to water, extracted three times with ethyl acetate, washed with common salt solution, dried on sodium sulfate, concentrated by evaporation in a vacuum and chromatographed on silica gel with dichloromethane/ethyl acetate. 203 mg of 11β-fluoro-7α-{5-[(2S)-2-(4,4,5,5,5-pentafluoropentanesulfinylmethyl)-pyrrolidin-1-yl]-pentyl}-estra-1,3,5(10)-triene-3,17β-diol is obtained. [α]D22=+11.8° (c=0.53% in methanol).
