Reaction Steps

To (1-ethyl-4-methyl-1H-imidazol-5-yl)methanol (754 mg, 5.4 mmol) in anhydrous dichloromethane (35 mL) was added thionyl chloride (2 mL). The mixture was stirred at room temperature overnight. Dichloromethane was evaporated and then co-evaporated with toluene (2×15 mL). The residue was dried in vacuo, affording 5-(chloromethyl)-1-ethyl-4-methyl-1H-imidazole hydrochloride (1.0 g, 95% yield). The product was used without further purification.
