実験手順

To a solution of 5-phenyl-1H-imidazole (5 g, 34.7 mmol) and K2CO3 (6 g, 41.6 mmol) in N,N-dimethylformamide (DMF) (20 mL) was added dimethylsulfamoyl chloride (4.11 mL, 38.2 mmol) drop wise at room temperature. The resulting mixture was stirred at room temperature for 4 h and then diluted with water (500 mL). The resulting solid was collected by vacuum filtration and dried to give the desired product (7 g). LC-MS: m/z 252 (M+H+).
