Versuchsvorschrift

To 2-hydroxymethyl-1-methylimidazole (874 mg) was added thionyl chloride (10 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 ethyl acetate, to give 2-chloromethyl-1-methylimidazole hydrochloride (1.15 g) as brown crystals.
