Abstract

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.
