Reaction Steps

To a solution of 3-bromo-4-chloroaniline (200 mg, 0.969 mmol) in dichloromethane (5 mL) was added triethylamine (0.374 mL, 2.91 mmol). The solution was cooled to 0° C. and benzenesulfonyl chloride (188 mg, 1.066 mmol) was added dropwise. After stirring at room temperature for 12 hours, the mixture was extracted with dichloromethane and the organic layer washed with water and brine (25 mL each). Drying over sodium sulfate, filtration and concentration afforded the title compound. LCMS: 346.1 (M+H)+.
