DABIGATRAN ETEXILATE SYNTHESIZING METHOD

摘要

The present invention relates to a dabigatran etexilate synthesizing method, the method being characterized by: using 2-(hydroxymethyl)-1H-benzimidazole -5-carboxy acid as raw material, thus greatly reducing the raw material and reagent costs for synthesizing benzimidazole, and having considerable economic value and market competitiveness; and not discharging a great deal of waste acid in a reaction process, thus having environmental value, and providing an optimal solution for large-scale industrial production of dabigatran etexilate.
