Versuchsvorschrift

A solution of oxalic acid (0.17 g) and 1-cyclooctylmethylimidazole (0.38 g) in ethanol (20 ml) was boiled for 0.25 hour, when evaporation of the solution afforded a white solid. Recrystallisation of the solid from ethyl acetate/ethanol/petroleum ether (b.p. 40°-60°) afforded 1-cyclooctylmethylimidazole oxalate as white needles, m.p. 141°-142° C.
