Versuchsvorschrift
To a solution (100 mL) of (1-ethyl-1H-imidazol-4-yl)methanol (5.80 g) in tetrahydrofuran was added thionyl chloride (14.59 g). The reaction mixture was heated under reflux for 1 hr and concentrated. Diethyl ether was added to the residue to allow crystallization, and the obtained crystals were collected by filtration, and washed with diethyl ether. The obtained crystals were recrystallized from methanol-tetrahydrofuran to give 4-chloromethyl-1-ethyl-1H-imidazole hydrochloride as colorless crystals (8.35 g, yield 100%).
