Telmisartan - Preparation Method

Open Data Verified Data

2-n-propyl-4-methylbenzoxazole-6-carboxylic acid and N-methylo-phenylenediamine are reacted in paraformaldehyde at 150 °c, the cyclization forms 2-n-propyl -4-methyl -6-(1-methylbenzimidazol-2-yl) benzimidazole. This is followed by alkylation with tert-butyl 2-(4-bromomethylphenyl) benzoate in dimethyl sulfoxide in the presence of potassium tert-butoxide. The resulting product was hydrolyzed in dimethylformamide with trifluoroacetic acid to give telmisartan.
