Popis: Telmisartan (1), a substituted dibenzimidazole derivative, is an antihypertensive drug, essentially used to control blood pressure. An improved, cost-effective, and impurity-free process for telmisartan (1) suitable for large-scale production is described here by addressing various process development issues. The overall yield obtained from this newly developed process is around 50% (over five steps) compared to the literature reported process (21%, over eight steps).
