実験手順

(Step 1) To a solution of 2N dimethylamine methanol solution (7.51 ml) in methanol (15 ml) was added dropwise a suspension of 2-[(acetylamino)methyl]-4-chlorobenzenesulfonyl chloride (2.12 g) in tetrahydrofuran (5 ml) under ice-cooling. The mixture was allowed to warm to room temperature, and stirred for 3 hr. The reaction mixture was quenched with water, and extracted with ethyl acetate. The extract was washed with saturated brine, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate) to give N-[5-chloro-2-(dimethylsulfamoyl)benzyl]acetamide (1.77 g) as a white solid.
