The resulting mixture was allowed to stir at room temperature for 20 min. Diluted with CH2Cl2 (30 ml) and washed the organic layer with 9% aq. Na2CO3 (10 ml) and brine (10 ml). Dried over anhydrous sodium sulfate, filtered and concentrated to a white solid, which was used without further purification. MS m/z=370.1 [M+H]+. Calc'd for C13H18F3N3O4S: 369.4.
