An original method has been developed for the synthesis of a number of pyridyl- and quinolylcarbonylarenecarboxylic acids by condensing anhydrides of aromatic dicarboxylic acids with picolinic and quinaldic acids.The characteristics of the IR spectra of the compounds synthesized are given, and their ring chain equilibrium transformations are discussed.It has been shown that the protonation of the nitrogen atom of the heterocycle stabilizes the cyclic form.
