Participants

Reaction Steps

Dry 1-methylimidazole (9.03 g, 0.11 mol) was mixed with 1-chloropentane (10.66 g, 0.1 mol) in a Schlenk round bottomed flask. The two components formed two layers, and acetonitrile (40 ml) was added to make the mixture homogeneous. The mixture was heated under reflux, under cover of dry nitrogen, for 5 hours. The resultant solution was allowed to cool to room temperature and evaporated to dryness in vacuo. The solid so formed was redissolved in acetonitrile (20 ml) and cooled to -13° C. for 5 days. This resulted in the formation of crystals which were isolated by Schlenk filtration and dried in vacuo for 48 hours. The yield of 1-pentyl-3-methyl imidazolium chloride was 8.2 g (69.9%), had a melting point of 58.2° C., m/z of 341.
