Page/Page column 10; 12, (2010/06/20)
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'-(1H-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.

Provided is a novel method of making 2-butyl-3-[[2'(1-trityl-1H-tetrazol-5-yl)biphen-4-yl]methyl]1,3-diazaspiro[4,4]non-1-ene-4-one, which can be converted to irbesartan. Also provided are methods of making irbesartan.
Preparation of acylated α-amino carboxylic acid amides
-
, (2008/06/13)
A method of preparing acylated α-amino carboxylic acid amides directly from amino nitriles in high yield and purity. The method involves acylating the amino nitrile with an acyl halide under Schotten-Baumann conditions, and hydrolyzing the resulting nitrile to the amide. The resulting acylated amino carboxylic acid amide precipitates and can be isolated by filtration in high purity.
