2-thiomethylbenzimidazolylbenzothiazole, Benzimidazole anologues and, Bis-benzimidazolesAbstract
Objective: The objective of this work is to synthesize new molecules with biological characteristics against some infectious germs.
Methods: The method of synthesis is based on the exploitation of the reactivity of the position-1 of the benzimidazole. It consisted of reacting the bis-benzimidazole 5 with the 1,2-dicloroethane in a solution of NaOH 2N (6,4%). The compound 6 is refluxed with ethanol with the different thioaryls to lead to compounds 7.
Results: Thus, a series of molecules derived from bis-benzimidazoles were synthesized including N-alkylated 6 and 7a-d. The characterization of these newly synthesized compounds was performed by NMR (1H and 13C) and mass spectroscopy methods.
Conclusion: The purified and characterized compounds 6 and 7a-d allow the development of a new chemical class of anti-infectives.
