실험 절차
15 g (54 mmol) of 4-bromophenacyl bromide and 5.2 g (55 mmol) of 2-aminopyridine were dissolved in 100 mL of ethanol. Then, 7.0 g of sodium hydrogen carbonate was added, and the resultant was heated under reflux for 6 hours. After completion of the reaction, generated crystals were filtered out, washed with water and ethanol, whereby 12.5 g (yield 85%) of 2-(4-bromophenyl)-imidazo[1,2-a]pyridine was obtained.
