Vorschrift

1,2-dimethylimidazole (7.2 g, made by Aldrich) and propyl iodide (12.7 g, made by Kanto Chemical) were stirred in toluene at 75° C. for 15 hours. After the end of the reaction, the reaction mixture was cooled to room temperature and the crude crystals formed were recovered. A mixed solvent of toluene and isopropanol was used for recrystallization. The crystals were dried in vacuo to obtain 1,2-dimethyl-3-propylimidazolium iodide (18.3 g).
