In view of the preparation of heterocyclic polymethine dyes, 2‐(methylpyridyl or quinolyl)‐benz‐X‐azoles were synthesized with the general reaction between carboxylic acids (or derivatives) and o ‐bifunctional compounds. The electronic spectra and the methyl proton chemical shifts are briefly discussed.
