Reaction Steps

A mixture of tert-butyl 4-[2-amino-4-(anilinosulfonyl)phenyl]-1,4-diazepane-1-carboxylate (176 mg, 0.39 mmol), methylsulfonyl chloride (0.040 mL, 0.47 mmol) and pyridine (0.285 mL, 3.51 mmol) in CH2CL2 (5 mL) was stirred at room temperature overnight. The reaction mixture was quenched with NaHCO3 aq (3×30 mL). The organic phase was separated, dried (MgSO4) and filtered. The volatiles were evaporated followed by purification of the oily residue by chromatography (SiO2, hexane/EtOAc 4:1) to give 110 mg of tert-butyl 4-{4-(anilinosulfonyl)-2-[(methylsulfonyl)amino]phenyl}-1,4-diazepane-1-carboxylate (yield 58%).
