A solution of fumaric acid (0.22 g) in hot ethanol (10 ml) was added to a solution of 1 -cyclooctylmethyl imidazole (0.38 g) in ethanol (4 ml). After boiling for 10 minutes the solution was evaporated to afford a white solid. Recrystallisation from ethyl acetate afforded 1-cyclooctylmethylimidazole hydrogen fumarate (0.42 g) as white needles, m.p. 147° to 148° C.
