Eight-point-five grams of trifluoromethanesulfonic acid was added dropwise to a solution of 6.1 g of 2,4-lutidine in 15 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 yield 2,4-lutidine trifluoromethanesulfonate (Lut+TfS−) as a colorless transparent liquid. The resulting salt had a melting point of 64.9° C.
