Procedure

To a solution of 3-chlorocarbonylbenzenesulfonyl chloride (5.0 g, 21 mmol) in THF (100 ml) was added methanol 1.7 ml (42 mmol) and the mixture was stirred at room temperature for 13 hours. After the reaction was completed, the resultant was concentrated under reduced pressure to give 5.14 g (21 mmol) of the titled compound as a pale purple solid. Yield: 100%.
