실험 절차

To 2-hydroxymethyl-1-propylimidazole (8.0 g) was added thionyl chloride (50 ml) at 0° C., and the mixture was heated for 30 minutes under nitrogen atmosphere at 90° C. The mixture was allowed to be at room temperature. The solvent was distilled off under reduced pressure, and the obtained residue was recrystallized from methanol-ethyl acetate, to give 2-chloromethyl-1-propylimidazole hydrochloride (4.3 g) as yellow crystals.
