摘要: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).
