The synthetic route of telmisartan and its derivatives was developed and improved. The condensation of o-phenylenediamine with various carboxylic acids gave benzimidazole derivatives, which were N-alkylated with methyl 4'-(bromomethyl)biphenyl-2-carboxylate to afford the corresponding title compounds. Nine novel title compounds were synthesized, and their structures were confirmed by 1H NMR, IR, MS spectra and elemental analyses. And the in vitro preliminary antihypertensive activity was evaluated by the method of aortic ring. Biological screening results dem-onstrated that some of the compounds displayed potential antihypertensive activity.

Key words: telmisartan, bioactivity, synthesis, derivative, angiotensin II receptor antagonist
