Reaction Conditions

Reaction Steps

A solution of sodium sulfite (153 mg, 1.21 mmol) and sodium bicarbonate (306 mg, 3.63 mmol) in water (3 mL) was treated with 2,4,5-trifluorobenzenesulfonyl chloride (280 mg, 1.21 mmol) and heated in a microwave reactor at 150° C. for 400 seconds. The resulting mixture was treated with 3-bromodihydrofuran-2(3H)-one (299 mg, 1.82 mmol) and then heated in a microwave reactor at 150° C. for 500 seconds. The mixture was cooled to 10° C. and the resulting solid filtered off and dried in vacuo to give the title compound (60 mg).
