A series of heterocyclic bases containing 2-(methyl-3-pyridyl)-X-azolo-pyridine was synthesized and the obtained bases were then quaternized.The structure of the salts were assessed by nmr and uv spectroscopy.From quaternary salts, styryl dyes were prepared and similarly characterized.The physical and spectroscopic data of the compounds were compared with those of the other isomers, previously described, and of the corresponding benzo-X-azole derivatives.
