Procedure

A hot solution of oxalic acid (0.225 g, 0.0025 mol) in dry ethanol (10 ml) was added to a solution of 1-(3,4-dimethylbenzyl)imidazole (0.46 g, 0.0025 mol) in hot ethanol (20 ml). After boiling for 0.25 h, the solution was evaporated to afford a white solid. Recrystallisation of the solid from ethanol/petroleum ether (b.p. 40°-60°) afforded 1-(3,4-dimethylbenzyl)imidazole hydrogen oxalate as a white solid, m.p. 92°-93°.
