الإجراء التجريبي

4-(2-aminoethyl)benzene sulfonamide (1 g, 5.0 mmol) and succinic anhydride (500 mg, 5.0 mmol) were combined in a round bottom flask containing dioxane (100 mL) and the slurry was heated to a reflux overnight. The white solid was filtered and washed with cold dioxane to yield the desired product (1.4 g, 4.6 mol, 92%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ 8.00 (s, 1H), 7.71 (d, J=8.1 Hz, 2H), 7.36 (d, J=8.1 Hz, 2H), 7.38 (s, 1H), 3.26 (m, 2H), 2.75 (t, J=7.1 Hz, 2H), 2.5 (m, 2H), 2.3 (t, J=7.1 Hz, 2H); (M+H)+ (301).
