실험 절차

Thionyl chloride (1.41 ml, 19 mmol) was slowly added to a solution of 2-(2-hydroxyethylthio)-1-methylimidazole (1.81 g, 11 mmol) in trichloromethane (20 ml) at 5° C. The mixture was stirred for 1 hour at 5° C. and then for 3 hours at ambient temperature. The volatiles were removed by evaporation and the residue azeotroped with toluene to give 2-(2-chloroethylthio)-1-methylimidazole hydrochloride (1.5 g, 77%).
