Versuchsvorschrift
To 2-hydroxymethyl-1-(2,2,2-trifluoroethyl)imidazole (1.40 g) was added thionyl chloride (14 ml), 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 solid was washed with ethyl acetate, to give 2-chloromethyl-1-(2,2,2-trifluoroethyl)imidazole hydrochloride (1.63 g) as brown crystals.
