Procedure
To a solution of (3-quinoxalin-2-ylphenyl)amine (120 mg, 0.545 mol) and 3-sulfamoylpropanoic acid (100 mg, 0.654 mmol) in dry DMF (3 mL), EDC (115 mg, 0.6 mmol) and HOBt hydrate (92 mg, 0.6 mmol) were added and the reaction mixture stirred at room temperature for 24 hrs. The solvent was evaporated in vacuo (45° C., 0.1 mbar) and the residue was triturated with DCM (10 mL) and filtered. The solid was triturated with hot acetonitrile, filtered hot and dried to afford 3-(aminosulfonyl)-N-[3-(2-quinoxalinyl)phenyl]propanamide (78 mg, 40%). LCMS calculated for C17H16N4O3S (M+H): 357.41. found 357.24. 1H-NMR (DMSO-d6, 400 Mhz) δH: 10.41 (1H, br.), 9.50 (1H, s), 8.53 (1H, m), 8.15 (2H, m), 8.02 (1H, m), 7.94-7.80 (3H, m), 7.55 (1H, m), 6.88 (2H, br.), 3.35 (2H, t, J=7.2 Hz), 2.85 (2H, t, J=7.2 Hz).
