ABSTRACT Benzimidazole and their derivatives represent a class of chemical compounds that play a vital role in medicinal chemistry. These compounds possess unique structural attributes, affording them a wide spectrum of significant biological activities. The biological activity of benzimidazole derivatives can be fine-tuned by changing the location and type of the substituents. Consequently, they have become the subject of extensive investigation and application in the field of drug development and discovery. In this study, a novel Mannich base incorporating a pyrimidine piperazine derivative was synthesized in a fast manner and with notable efficiency, utilizing benzimidazole as the central structural motif. The benzimidazole core structure offers a great advantage in terms of substituent substitution, allowing for the creation of compounds with diverse biological activities. By varying the position and type of substituents on the benzimidazole molecule, the resulting derivatives can be modified to effect specific changes in biological activities. This flexibility in substitution provides a powerful tool to explore and optimize the potential biological effects of benzimidazole compounds. It opens up possibilities for designing molecules with enhanced therapeutic properties and targeted interactions with biological systems. The ability to conveniently modulate the activities of benzimidazole derivatives through structural modifications makes them valuable candidates for organic synthesis and drug design. The resulting compound underwent comprehensive characterization by melting point, Thin Layer Chromatography, 1H-NMR and FT-IR spectroscopy. The preliminary antimicrobial efficacy of the newly synthesized Mannich base was evaluated utilizing the disk diffusion method against E. coli and S. aureus.
