HCID 231822231-Heptyl-3-[4-(4-methoxyphenyl)butyl]-2-methylimidazolium bromide

Conditions

Temperature
140 °C

Procedure

A mixture of 2.50 g (0.0139 mole) of 1-heptyl-2-methyl-1H-imidazole and 3.37 g (0.0139 mole) of 1-(4-bromobutyl)-4-methoxybenzene is heated at 140° C. for about 2 hours. Follow the progress of the reaction by thin-layer chromatography on silica gel (methanol: 1M sodium chloride, 95:5). At the completion of the reaction, the cooled reaction product is triturated thoroughly with ether and on drying, provides the title compound.
