Procedure

A solution of 0.61 g (3.3 mmol) of 4-bromo-N-methylaniline and 0.5 mL (3.92 mmol) of benzenesulfonyl chloride in 5 mL of pyridine was stirred for 12 h at rt. After that time the pyridine was removed by azeotropic distillation with heptane. The residue was purified by chromatography on silica (hexanes:EtOAc, 9:1) to give the title compound.
