Abstract: The present invention provides an improved and commercially viable process for preparation of irbesartan intermediate, 1-[(2?-cyanobiphenyl-4-yl)methyl]-2-n-butyl-4-spirocyclopentane-2-imidazolin-5-one, substantially free of 1-[(2?-cyanobiphenyl-4-yl)methyl]-2-n-propyl-4-spirocyclopentane-2-imidazolin-5-one impurity, thereby producing irbesartan substantially free of the undesired propyl analog impurity, namely 2-propyl-3-[[2?-(1H-tetrazol-5-yl)[1,1?-biphenyl]-4-yl]methyl]-1,3 -diazaspiro[4.4]non-1-en-4-one. The present invention also provides a process for preparation of irbesartan substantially free of tin content. The present invention further provides a commercially viable process for preparation of irbesartan in high purity and in high yield.

Abstract: There was provided a process for preparing candesartan cilexetil, the said process comprises hydrogenating a solution of trityl candesartan cilexetil in an alcohol with hydrogen in the presence of a palladium catalyst. Mixture of toluene and methanol was added to 1-(Cyclohexyloxy carbonyloxy)ethyl-2-ethoxy-1-[[2?-(N-triphenylmethyltetrazole-5-yl)biphenyl-4-yl]methyl]benzimidazole-7-carboxylate and hydrogenated at room temperature with hydrogen at atmospheric pressure in the presence of palladium on carbon until the hydrogen uptake was ceased. Filtered over celite bed, washed the bed with a mixture of toluene and methanol, filtrate was collected and concentrated. Co-distilled with acetonitrile, acetonitrile was added, stirred at room temperature, cooled to 0° C. stirred, filtered, washed with chilled acetonitrile and dried to get candesartan cilexetil.
