Phenacylpyridinium bromide, p-chlorophenacylpyridinium bromide, and p-methylphenacylpyridinium bromide were reacted with para-substituted dibenzalacetones in presence of ammonium acetate in glacial acetic acid to give 2,4-diaryl-6-(β-phenylvinyl)pyridines in 45-65 percent yields.Ammonium acetate in acetic acid was used as an aza cyclization agent.The structures of the resulting pyridines were confirmed by IR and NMR spectral data and elemental analyses.
