Reaktionsschritte
A mixture of 1,4,5-triphenylimidazol-2-one (15.3 g), dibromoheptane (50.6 g) and potassium carbonate (13.8 g) was heated at reflux temperature in dry butanone (750 ml) for 20 hours. The mixture was cooled, filtered and the filtrate evaporated to an oil which was chromatographed on silica gel (hexane/ethyl acetate) to give 1,4,5-triphenyl-3-(7-bromoheptyl)imidazole-2-one (11.1 g, 46%) as an oil.
