Procedure
A solution of 3-chlorobenzenesulfonyl chloride (3.0 g) in dioxane (40 mL) was treated with a mixture of sodium hydrogen carbonate (2.7 g), sodium sulfite (3.6 g) and water (20 mL), and the resulting mixture was stirred at 75° C. for 30 minutes. The mixture was cooled to room temperature and concentrated under reduced pressure. The residue was triturated with ethanol to afford the title compound as a white solid (0.20 g).
