1-(4-Chlorophenyl)imidazole (0.37 g, 2.07 mmol) is dissolved in THF (5 ml) and subsequently admixed with methyl iodide (1.47 g, 10.4 mmol) and allowed to stand for 20 hours. The precipitate formed is subsequently filtered off and washed with ethanol and with petroleum ether and subsequently dried under reduced pressure. This gives 0.46 g of 1-(4-chlorophenyl)-3-methylimidazolium iodide.
