Reaction Steps

4,5-dichloroimidazole (10.0 mmol, 1.370 g) and KOH (11.0 mmol, 0.617 g) were placed in a 50 mL round bottom flask with 10 mL acetonitrile. The mixture was brought to reflux (85° C.) and stirred 1 h until KOH was consumed. 2-Bromomethylnapthalene (10.00 mmol, 2.211 g) was added and the solution was stirred 2.5 hours. KBr was removed by vacuum filtration and benzyl bromide (10 mmol) was added to the filtrate. The mixture was stirred at reflux for 1.5 hours. The white precipitate was collected by filtration and analyzed. 1H NMR (500 MHz, d6-DMSO): δ 5.51 (2, 2H), 5.65 (s, 2H), 7.94-8.02 (m, 8H), 7.95-8.06 (m, 4H), 9.63 (s, 1H) ppm.
