Procedure

tert-Butyl 4-{4-(anilinosulfonyl)-2-[(methylsulfonyl)amino]phenyl}-1,4-diazepane-1-carboxylate (0.077 g, 0.147 mmol) was dissolved in MeOH, and ether saturated with HCl gas was added. The mixture was stirred at room temperature for 4 h and then concentrated. The crude solid was dissolved in a small amount of MeOH, and ether was added. The precipitate was collected and dried to give 30 mg of the pure product as the HCl salt (yield 48%): 1H NMR (DMSO-d6) δ 7.72–7.70 (m, 1H), 7.46–7.42 (m, 1H), 7.25–7.20 (m, 3H), 7.14–7.09 (m, 2H), 7.03–6.99 (m, 1H), 3.45–3.15 (m, partly obscured by solvent signal, HDO, 6H), 2.96 (s, 3H), 2.02–1.95 (m, 2H); MS (posES-FIA) m/z=425 (M+H+).
