AN IMPROVED PROCESS FOR THE PREPARATION OF OLMESARTAN MEDOXOMIL
摘要
<p>The present invention provides an improved process for the preparation of olmesartan medoxomil with high yield, high degree of purity with fewer impurities. Specifically, the invention provides a method for the preparation of an intermediate of olmesartan i.e. 4-(lhydroxy- 1 -methylethyl)-2-propyl-1 -[4-(2-trityltetrazol-5-yl)phenyl]-phenyl methyl imadazole-5- carboxylic acid sodium salt. The said intermediate is further used for the preparation of olmesartan medoxomil.</p>
