Procedure
(Step 3) To a solution of N-(5-fluoro-2-sulfamoylbenzyl)acetamide obtained in Step 2 (2.7 g) in ethanol (20 ml) was added hydrochloric acid (10 ml) at room temperature, and the mixture was stirred with heating under reflux for 3 hr, and then overnight at 80° C. The solvent was evaporated under reduced pressure. The residue was collected by filtration, and washed with diethyl ether to give 2-(aminomethyl)-4-fluorobenzenesulfonamide hydrochloride (1.49 g) as a white solid.
