Procedure

In a 25 ml one-necked flask, there is dissolved 0.240 g (1.024 mmol) of 4,5-diphenyl-1-methylimidazole, which was obtained according to Zeitschrift fuer Naturforschung, B: Chemical Sciences (2003), 58(4), 305-310, in 10 ml of toluene and then 183 μl (1.536 mmol) of benzyl bromide are added. After 2 days of heating under reflux, the reaction medium is concentrated under reduced pressure. The residue is taken up in 50 ml of diisopropyl ether. The precipitate formed is drained, washed twice with 5 ml of diisopropyl ether and then dried under reduced pressure. There is thus obtained 0.480 g (100%) of 3-benzyl-4,5-diphenyl-1-methylimidazolium bromide, in the form of a yellow solid, used as it is in the next step, whose characteristic is the following:
