Benzoylacetanilide and fourteen of its substituted derivatives were brominated to give α-bromobenzoylacetanilides (I). The spectral data of I indicate that they exist mainly in the keto form. Reaction of I with phenylhydrazine yielded 4-phenylazo-1,3-diaryl-2-pyrazolin-5-ones (IV). Treatment of I with thiourea and thioacetamide gave 2-amino-4-arylthiazole-5-carboxanilides (XII) and 2-methyl-4-arylthiazole-5-carboxanilides (XIII), respectively. With excess of concentrated sulfuric acid or polyphosphoric acid, α-bromobenzoylacetanilides (I) were converted into 3-bromo-4-aryl-2-quinolones (XVI). Structural assignments were based on the elemental and spectral analyses.
