실험 절차
2-(4-Chloro-2-methoxy-phenyl)-ethenesulfonyl chloride (0.50 g, 1.87 mmol) was added slowly to a solution of 2-amino-5-methyl-benzenesulfonamide (0.38 g, 2.05 mmol) in anhydrous pyridine (10 mL) and the reaction mixture was stirred for 18 hours at room temperature. The solvent was removed in vacuo and the residue was dissolved in ethyl acetate (30 mL). The organic phase was washed with 1 M hydrochloric acid and brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. Purification by column chromatography gave 0.42 g (54% yield) of the title compound.
