실험 절차

To 5 ml of dry acetonitrile were added 1.4 g of 1-ethoxycarbonylimidazole and 2.55 g of methyl 4-bromomethylcinnamate, 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 2.9 g of 1-ethoxycarbonyl-3-[4-(2-methoxycarbonylvinyl)benzyl]imidazolium bromide.
