실험 절차

To a suspension of 4-chloro-3-sulfamoyl-benzoic acid (50 g, 212 mmol) in 500 mL ethanol is bubbled HCl gas for 10 minutes. The resulting suspension is then heated at reflux for 16 h, cooled and concentrated in vacuo. The resulting residue is recrystallized from isopronanol to yield 55.9 g (99%) of the title compound as an off-white solid.
