Abstract
The interaction of equimolar amounts of 2-ethoxycarbonylaminopyridine with phenacyl bromides in acetonitrile leads to 2-aryl-1-(ethoxycarbonyl)-2-hydroxy-2-phenyl-2,3-dihydro-1H-imidazo[1,2-a]pyridinium bromides. When these compounds are boiled in acetic anhydride followed by treatment with potassium carbonate, 2-arylylimidazo[1,2-a]pyridines are formed.
