A series of benzimidazol-2-ylamides of 4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carboxylic acids was prepared in a search for biologically active compounds. These compounds exist in the crystal exclusively in the amide form, while in solution amide↔imide tautomerism is observed. The results of a study of the antithyroid and antituberculosis activities of these compounds are given.

Prolonged treatment of ethyl 1-alkyl-4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carboxylates with refluxing phosphorusoxychloride gives not only the target 4-chloro derivatives but is also accompanied by a marked loss of the 1-N-alkyl groups to form the side product 2,4-dichloro-3-ethoxycarbonylquinoline.
