Participants

Reaction Steps

In a 25 ml one-necked flask, 1.4 g (17.05 mmol) of 1-methylimidazole are dissolved in 15 ml of 1,2-dichloroethane and then 4.89 g (20.46 mmol) of 3-trifluoromethylbenzyl bromide are added. After heating overnight at 80°, 50 ml of diethyl ether are added. The oil, which is then separated by decantation, is crystallized from a mixture of ethyl acetate and tetrahydrofuran (2/1 by volume). The crystals thus obtained are drained and then dried under reduced pressure. 3.06 g (56%) of 1-methyl-3-(3-trifluoromethylbenzyl)imidazolium bromide are thus obtained in the form of off-white crystals, used as they are in the next step, whose characteristic is the following:
