Procedure
The starting material, 4-chloro-1,3-dimethylimidazoline-2-thione was first prepared by adding dropwise and intimately admixing 5.68 grams (0.04 mol) of methyl iodide to a solution of 4.0 grams (0.0343 mol) of 5-chloro-1-methylimidazole in 25 milliliters of methylene chloride. The resulting mixture was stirred overnight at room temperature whereupon a crystalline product was found to have formed. The latter was recovered with cold methylene chloride to obtain 1,3-dimethyl-5-chloroimidazolium chloride.
