Procedure

A mixture of 6.0 g of 1,2,3-trimethyl-1H-imidazolium iodide, 1 g of potassium hydroxide and 6 ml of 1-naphthaldehyde in 25 ml of methanol is refluxed for 15 minutes during which time a precipitate is formed. The reaction mixture is cooled and 5 ml of water is added. The solid is filtered off, dried, and crystallized from absolute ethanol to yield 3.7 g of the title compound, melting point 251°-253° C.
