반응 단계

A mixture of 2,4,5-triphenylimidazole (11 g), ethyl 8-bromooctanoate (18.64 g), anhydrous potassium carbonate (51.3 g) and dry butanone (350 ml) was heated at reflux for 26 h. The cooled reaction mixture was filtered to remove inorganics and the filtrate was evaporated to dryness in vacuo. The residue was stirred in hexane and unreacted 2,4,5-triphenylimidazole was collected by filtration (3.1 g). The filtrate was cooled and a white precipitate was collected. Recrystallisation from hexane gave 1-(7-ethoxy-carbonyl-heptyl)-2,4,5-triphenylimidazole (8.37 g, 48.4%) as a white solid, m.p. 65°-7°.
