The reaction was cooled, poured into water (120 ml) and the mixture was extracted with methylene chloride. The organic layer was dried over sodium sulfate, filtered and the filtrate concentrated. The residue was recrystallized from ethyl acetate and hexane to give 760 mg (45%) of the desired sulfone: mp 130-132° C. Anal. Calc'd. for C16H13FO4S2 (MW 352.41): C, 54.53; H, 3.72; S, 18.20. Found: C, 54.20; H, 3.51; S, 18.40.
