摘要: A process for preparing telmisartan by reacting 2-n-propyl-4-methyl-6-(1′-methylbenzimidazol-2′-yl)benzimidazole with a compound of formula (IV) wherein Z is a leaving group, to obtain the compound 2-cyano-4′-[2″-n-propyl-4″-methyl-6″-(1′″-methylbenzimidazol-2′″-yl)benzimidazol-1″-ylmethyl]biphenyl, and subsequently hydrolyzing the nitrile function to obtain the acid function.
