摘要

Benzimidazole nucleus has a ubiquitous presence in several bioactive molecules and is considered to be the 'privileged sub-structure'for drug design [1]. Various benzimidazole derivatives have been found to possess anticancer, antiviral and antihypertension properties [1-3]. Benzimidazoles are also important intermediates in organic synthesis [4, 5].
