Procedure

Twenty-five grams of trifluoromethanesulfonic acid was added dropwise to a solution of 16 g of N-ethylimidazole in 20 ml of ethanol at 0° C. The solution was returned to room temperature, stirred overnight, and dried in vacuo at 60° C. for 16 hours to give N-ethylimidazole trifluoromethanesulfonate (EtIm+TfS−) as a colorless transparent liquid. The resulting salt had a melting point of 8.3° C. (literature value: 7.8° C.).
