Versuchsvorschrift

A solution of 1-[2-(6,6-dimethylbicyclo[3.1.1]heptan-2-yl)ethyl]imidazole (0.8 g, 3.67 mmol) hot ethanol (10 ml) was added to a solution of oxalic acid (0.3 g, 3.33 mmol) in hot ethanol (20 ml). After boiling the reaction mixture for 0.15 h, the solution was concentrated under reduced pressure to afford a white solid. Recrystallisation of the solid from propan-2-ol gave 1-[2-(6,6-dimethylbicyclo[3.1.1]heptan-2-yl)ethyl]imidazole hydrogen oxalate, m.p. 172°-174°.
