3-[4-(2-bromoacetyl)phenyl]-1-methylquinolin-2(1H)-one. The latter reacted with pyridine, 4-methylpyridine, quinoline, benzo[f]quinoline, and triphenylphosphine to afford the corresponding quaternary salts, and its reactions with thioacetamide, thiourea, 2-aminopyridine, and 2-aminopyrimidine led to the corresponding thiazole, imidazo[1,2-a]pyridine, and imidazo[1,2-a]pyrimidine derivatives containing a 2-oxoquinoline
