Oxalic Acid → HCID 20574504, compound

Participants

Reaction Steps

To 1-n-butylimidazole (0.31 g; 0.0025 mole) in methanol (5 ml) was added oxalic acid (0.225 g; 0.0025 mole) in methanol (5 ml). After heating under reflux for 5 minutes the mixture was evaporated under reduced pressure to afford a white solid. Recrystallisation of the solid from ethanol/ether (1:4) afforded 1-n-butylimidazole oxalate as colourless needles, m.p. 82° to 83° C. (Found: C,50.2; H,6.5; N,13.05. Calc. for C9H14N2O4 :C,50.45; H,6.55; N,13.1%).
