Procedure

Methyl 2-methoxy-5-sulfamoylbenzoate (4.91 g, 20 mmol) was dissolved in methanol (30 mL). 2 N aqueous sodium hydroxide (30 mL, 60 mmol) was added, and the mixture was stirred at room temperature for 1 hour. The reaction mixture was poured into 2 N hydrochloric acid, and the separated solid was filtered to give the title compound (4.55 g, 98.3%) as a white solid.
