실험 절차
Dissolving 5.8 g (29 mmol) of phenacyl bromide and 5.0 g (29 mmol) of 2-amino-5-bromopyridine into 50 milliliter of ethanol, adding 3.6 g of sodium hydrogen carbonate, the resultant suspension was refluxed under heating for 6 hours. After completion of the reaction, separation with filtration was carried out and resultant crystals were washed with water and ethanol, thereby obtaining 6.4 g of 6-bromo-2-phenyl-imidazo [1,2-a] pyridine (yield: 81%).
