Procedure
A solution of 9-fluoro-11β-hydroxy-17-(methylthio)androsta-1,4,16-trien-3-one (100 mg, see Example 1B) in 30 ml of xylene containing 4.0 g of benzoic anhydride and 300 mg of sodium methoxide is stirred at 130° C for 48 hours. The product is then isolated and chromatographed over silica gel to yield 80 mg of the title compound, melting point 220°-222° C.
