A new process for the preparation of irbesartan |
| abstract |
A process for the preparation of Irbesartan or a pharmaceutically acceptable salt thereof comprising the step of coupling the 1-pentanamidocyclapentanecarboxamide of formula (V) with 4'-substituted methyl biphenyl-2-carbonitrile or 1-(4'-substituted methyl biphenyl-2-yl)-1H-tetrazole wherein tetrazole can be protected or unprotected to obtain the N-[(2'-cyanobiphenyl-4-yl)methyl]-1-pentanamidocyclopentanecarboxamide or N -[1-({[2'-(1 H- tetrazol-1-yl)biphenyl-4-yl]methylamino)methyl)cydopentyl]pentanamide wherein tetrazole can be protected or unprotected that is further processed to Irbesartan or a pharmaceutical acceptable salt thereof. |
