Abstract

A process utilizes the tetrazole functional group to direct lithiation at the ortho position of a phenyltetrazole and generate a nucleophilic aryllithium species which then undergoes reaction with an electrophile to generate a 2-substituted 1-(tetrazol-5-yl)benzene. The process is useful in the production of intermediates in the synthesis of angiotensin II antagonists. This novel process is a more cost effective and versatile route for the large-scale preparation of these key intermediates.
