Reaction Steps

A solution of tert-butyl (4-(4-sulfamoylphenoxy)butyl)carbamate (0.72 g, 2.09 mmol) in TFA (5.0 mL) and DCM (5.0 mL) was stirred at rt for overnight. After the solvent was evaporated under a steam of N2, the reaction mixture was dissolved in water (20.0 mL) and acetonitrile (5.0 mL) and lyophilized to afford 4-(4-aminobutoxy)benzenesulfonamide as a yellow solid (0.906 g) containing TFA. 1H NMR (400 MHz, DMSO) 7.74-7.72 (m, 4H), 7.20 (s, 2H), 7.06 (d, 2H), 4.06 (t, 2H), 2.89-2.82 (m, 2H), 1.80-1.75 (m, 2H), 1.71-1.65 (m, 2H); MS (ESI), 245.1 (M+H)+.
