Benzenesulfonyl chloride → N-(3-Nitrophenyl)benzenesulfonamide

Participants

Reaction Steps

To 6.17 g (44.7 mmol) of 3-nitroaniline and 8.41 mL (482 mmol) of N,N-diisopropylethylamine in 150 mL of anhydrous diethyl ether was added 5.14 mL (40.2 mmol) of benzenesulfonyl chloride. The mixture was heated to reflux under nitrogen with stirring for 16 h, cooled and the resulting two-phase mixture scratched to crystallize the insoluble oil. After decanting the ether layer, the derived solid was dissolved in 300 mL of dichloromethane and the solution washed with 2 N HCl (3×200 mL), saturated NaHCO3 (200 mL), brine (200 mL), dried (NaO2SO4) and concentrated to give 9.62 g (86%) of the title compound as a light tan solid.
