Abstract
The reactions of o-phenylenediamine and 3,4-diaminotoluene with such acids as 3-cyclohexylpropionic, 4-phenylbutyric, 4-cyclohexylbutyric, 3,3-diphenylpropionic, and 3,4-dimethoxyphenylacetic resulted in the formation of the corresponding 2-substituted benzimidazoles. These compounds were transformed into methane-and benzenesulfonamide derivatives. The benzimidazole derivatives obtained were tested in vitro for their tuberculostatic activity. Compounds with good activity (MIC 6.2-25 µg/ml) have been found.
