2-Aminopyridine betaine (1-carboxymethyl-2-aminopyridinium inner salt) forms crystalline complexes with HCl, HBr and HClO 4 . These complexes on heating in ethanol cyclize to 1H-2-oxo-2,3-dihydroimidazo[1,2-a]pyridinium chloride (1Ax), bromide (2Ax) and perchlorate (3Ax), respectively. Infrared spec
