Procedure

A mixture of 6.0 g of 1,2,3-trimethyl-1H-imidazolium iodide, 1g of potassium hydroxide, and 6 g of p-chlorobenzaldehyde is refluxed in 25 ml of absolute ethanol for 15 minutes during which time a precipitate is formed. The reaction mixture is cooled, 5 ml of water is added, and the solid is filtered off and dried. Crystallization from absolute ethanol yields 5.4 g of the title compound, melting point 266°-268° C.
