Procedure
2,5-Dimethoxy-N-[2-[(phenylsulfonyl)amino]-4-(1-piperazinyl)phenyl] benzenesulfonamide was synthesized from of N-{2-amino-5-(4-t-butyloxycarbonyl-piperazinyl)-phenyl}benzenesulfonamide and 2,5-dimethoxybenzenesulfonylchloride (57 mg, 0.239 mmol) according to general method 3 to give 60 mg of a purple solid. MS (posES-FIA) m/z=Found: 533.1; Calcd: 533.14; 1H-NMR δ 7.68–7.48 (m, 5H), 7.16–7.05 (m, 4H), 6.69 (dd, 1H), 6.42 (d, 1H), 4.03 (s, 3H), 3.69 (s, 3H), 3.26–3.10 (m, 8H).
