Procedure

A mixture of 1.5 g of 2-(trimethylsilyl)ethyl 3-{[4-(methoxycarbonyl)phenyl](methyl)sulfamoyl}benzoate, a solution of TBAF in THF (1.0 M, 7.0 mL), and 15 mL of THF was stirred at room temperature for 2 hours. To the reaction mixture was added 0.2 M hydrochloric acid, followed by extraction with ethyl acetate. The organic layer was washed with 0.2 M hydrochloric acid, water, and saturated brine in this order, then dried over anhydrous sodium sulfate, and concentrated under reduced pressure to obtain 1.11 g of 3-{[4-(methoxycarbonyl)phenyl](methyl)sulfamoyl}benzoic acid as a colorless solid.
