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

In a previous paper (1) we reported the formation of the cycloadduct V, in the borohydride reduction of the pyridinium salt I. If the reduction is carried out at -45" in 0.8N methanolic NaOH the insoluble product IV is formed (60% yield), containing only traces of compound V. However, reductions car
