Reaction Steps

A solution of Na2SO3 (400 mg, 3.2 mmol) and NaHCO3 (270 mg, 3.2 mmol) in H2O (10 mL) was treated slowly with a solution of 4-methoxy-3-nitrobenzenesulfonyl chloride (400 mg, 1.6 mmol) in acetone (3 mL), heated to 50° C. for 2 hours, cooled to room temperature, and washed with dichloromethane. The aqueous wash was filtered through cotton, lyophilized, suspended in methanol, filtered, concentrated, and dried under vacuum to provide the desired product.
