실험 절차
To a stirred solution of 2-ethylimidazole (100 g) and triethylamine (115 g) in chloroform (800 ml) at 0° C. is added a solution of dimethylsulfamoyl chloride (153 g) in chloroform (200 ml). The mixture is stirred overnight at room temperature. Water (1.5 liter) is added to the reaction mixture after which the organic layer is separated and concentrated. The residue is dissolved in ethyl acetate (1 liter) and washed with water, and then dried over sodium sulfate and concentrated. Distillation gives 1-dimethylsulfamoyl-2-ethylimidazole (182 g) as a colorless liquid.
