Versuchsvorschrift

To a solution of (5-chloro-1-methyl-1H-imidazol-4-yl)methanol (397 mg, 2.7 mmol) in anhydrous dichloromethane (20 mL) was added thionyl chloride (1 mL). The mixture was stirred at room temperature for 2 hours. Dichloromethane was evaporated and then co-evaporated with toluene (2×10 mL). The residue was dried in vacuo, affording 5-chloro-4-(chloromethyl)-1-methyl-1H-imidazole hydrochloride (550 mg, 99% yield). The product was used without further purification.
