Yield: 98%

Reaction Conditions:

with ammonium iodideSchlenk technique;Reflux;

Steps:

1-butyl-3-methylimidazolium iodide
1-butyl imidazole put 1.82 mmol (0.24 mL) and 2.18 mmol NH4I (317 mg) and trimethyl ortho formate 9.1mmol (1 mL) in a Schlenk reaction tube and reflux under air or N2. Confirming that the protonated imidazole disappears then removed trimethyl ortho formate remaining under vacuum, and then, a small amount of the protonated imidazole deprotonation was passed through a basic alumina dissolved in ethyl acetate. After having passed through this solution, putting them in a vacuum and the product was confirmed by NMR. Yield: 98%
