Procedure
A solution of fumaric acid (0.5 g, 4.31 mmol) in boiling ethanol (15 ml) was added to a solution of 1-[2-(1-Adamantyl)ethyl]imidazole (1.0 g, 4.34 mmol) in hot ethanol (10 ml). After boiling for 0.15 h, the mixture was concentrated to afford a white solid. Recrystallisation of the solid from ethyl acetate gave 1-[2-(1-adamantyl)ethyl]imidazole hydrogen fumarate as a colourless solid, m.p. 117°-118°.
