실험 절차

To a solution of N-methyl-4-bromophenylsulfonamide (2.5 g, 10 mmol) in DMF (20 mL) at room temperature was added in portions NaH (264 mg, 11 mmol). The mixture was stirred for 45 minutes and then p-methoxybenzylchloride (1.49 mL, 11 mmol) was added dropwise. The mixture was stirred for 1 hour, quenched with water and the precipitate which formed was collected by filtration and dried in vacuo at 60° C. to afford 3.6 g (97%) of N-methyl-N-(4-methoxybenzyl)-4-bromophenylsulfonamide.
