Reaction Conditions

Reaction Steps

A mixture of 100 mg of 17α-acetoxy-6α,7α-epoxy-2-oxa-4-pregnene-3,20-dione, 200 mg of potassium hydrogen fluoride and 1 ml of dimethyl sulfoxide was heated at 140° C. for 20 minutes. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with a saturated aqueous solution of sodium hydrogen carbonate, and dried over anhydrous magnesium sulfate. The solvent was evaporated, and the crude product was purified by TLC [developing solvent: chloroform/acetone (50/1)] to give 20 mg of 17α-acetoxy-6-fluoro-2-oxapregna-4,6-diene-3,20-dione.
