Reaction Steps

To a suspension of sodium hydride (60%, 0.07 g (1.75 mmol)) in DMF (2.0 ml), 2′,4′-dichloro-p-toluenesulfonanilide (0.50 g (1.58 mmol)) was added with stirring at room temperature. To the resulting mixture, after 15 minutes' stirring at room temperature, dimethyl sulfate (0.17 ml (1.80 mmol)) was added dropwise. After 15 hours' stirring at room temperature, the reaction mixture was poured into water and extracted with ethyl acetate. The extract was washed with water and saturated sodium chloride solution, successively, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The crystals separated were filtered and washed with diisopropyl ether to give 0.38 g (73%) of the title compound.
