ABSTRACT: The present study deals with the heterocyclization of Schiff bases of (5-Benzoyl-benzimidazol-1-
yl)-acetic acid hydrazide [BBAH] into (2H)-Pyrrole-2-ones derivatives. One of the hydrazide i.e. 2-hydroxy
benzoic acid hydrazide (salicylhydrazide) and their condensed product play a vital role in medicinal
chemistry. More particularly and recently these types of compounds have been found in the treatment of T.B.
and other chemotherapeutic diseases. Hence, it was thought of interest of merging of both pyrrole and
benzimidazole hydrazide moieties may enhance the drug activity of compound up to some extent or might
possess some biological activity. From this point of view the objective of present works to prepare new
derivatives of benzimidazole hydrazide containing a pyrrole moiety. Hence The present study deals with the
heterocyclization of Schiff bases of (5-Benzoyl-benzimidazol-1-yl)-acetic acid hydrazide [BBAH] into (2H)-
Keywords: (5-Benzoyl-benzimidazol-1-yl)-acetic acid hydrazide, Pyrrole, spectral studies.
