Reaction Steps

A mixture of 4-chloro-3-nitrobenzenesulfonylchloride (1 g, 3.9 mmol), 3-chloroaniline (0.5 mL, 4.7 mmol) and pyridine (1.6 mL) in CH2Cl2 (2 mL) was stirred at room temperature. The reaction was quenched with NaHCO3 (sat aq solution, 30 mL×3). The organic phase was separated, dried (MgSO4), and filtered. The volatiles were evaporated and the residue was purified by column chromatography (SiO2, pentane:EtOAc, 4:1) to give 4-chloro-N-(3-chlorophenyl)-3-nitrobenzenesulfonamide; MS (posESI) m/z=349.2 (M+H+).
