Reaction Steps

Under N2, chlorosulfonic acid (1.5 g, 12.87 mmol) was diluted in CCl4 (2 mL) and cooled to 0° C. Then 3-phenyl-1,3-oxazolidin-2-one (280 mg, 1.72 mmol) was diluted in CCl4 (2 mL) and added slowly to the reaction mixture. The reaction mixture was stirred for two hours at 0° C. The reaction was then slowly quenched with ice water (4 mL) and extracted with CCl4 (3×4 mL). The organic extracts were dried over sodium sulfate and concentrated to give 4-(2-oxo-1,3-oxazolidin-3-yl)-benzenesulfonyl chloride which was used without purification.
