A series of novel 5-amino-1,3,4-thiadiazole-2-thiol and 1,3,4-thiadiazole-2,5-dithiol derivatives of benzimidazole were synthesized through nucleophilic substitution reaction of 5-substituted-2-(chloromethyl)-1H-benzimidazole, structures of the synthesized compounds were proved by spectral methods of analysis (FT-IR, 1H and 13C NMR). All the target compounds were screened for their antibacterial activity toward gram-negative (E.coli, P. aeruginosa) and Gram-positive (B. subtilis, S. aureus) bacteria, most of the synthesized derivatives exhibited good to moderate activity toward both Gram-positive (B. subtilis, S. aureus) and Gram-negative (E.coli, P. aeruginosa) bacteria.

Substituted 1H-benzimidazoles, pyrazolones, and pyrazoles have been synthesized by the condensation of ortho-phenylenediamines and phenylhydrazines, respectively, with ethyl 4-chloro-3-oxobutanoate in good yields. The present approach is novel, straightforward, and being reported for the first time with ethyl 4-chloro-3-oxobutanoate.
