Procedure

To a solution of 37.0 g (0.45 mol) of 1-methylimidazol in 200 ml of 1,1,1-trichloroethane was added dropwise a solution of 68.7 g (0.45 mol) of p-chloromethylstyrene in 100 ml of 1,1,1-trichloroethane at room temperature while stirring. After the addition, the mixture was stirred at 65° C. for 10 hours. The resulting product was separated from the reaction mixture, washed with 100 ml of 1,1,1--trichloroethane twice, and dried at 65° C. at 0.1 mmHg for two hours to give 1-methyl-3-(4-vinylbenzyl)imidazolium chloride (MVBI.Cl) as a pale yellow solid. Yield was 52.8 g (50%).
