Versuchsvorschrift
To 5 ml of dry acetonitrile were added 1.7 g of 1-benzoylimidazole and 2.6 g of methyl 4-bromomethylcinnamate, and the mixture was stirred for 5 hours at room temperature. The precipitated crystals were collected by filtration and recrystallized from acetonitrile/diethyl ether to yield 3.5 g of 1-benzoyl-3-[4-(2-methoxycarbonylvinyl)benzyl]imidazolium bromide.
