Reaction Steps

3-(Aminosulfonyl)benzoic acid (603 mg, 3.0 mmol) was heated at 80° C. in CH3OH (3 mL) with 3 drops of concentrated sulfuric acid for 60 hours. The reaction mixture was diluted with EtOAc (20 mL), washed with water, brine, and dried (Na2SO4). The solvent was evaporated to afford the product (630 mg, 98%) as a white solid. MS (ES+) m/z 216 [M+H]+.
