Indole and benzimidazole, as well as their substituted derivatives, are attracting attention due to their synthetic utility and wide range of pharmacological effects. N-substituted fused heterocyclic compounds are usually physiologically active and could be used to treat cancer. Because of its solubility in water, mild basic character, ease of availability, eco-friendliness, and benign nature, K2CO3 has been found to be essential for a variety of processes. The effect of the catalyst ratio utilised anhydrous K2CO3 for its N-1 alkylation or arylation of indole-3-carboxaldehyde and 2-acetylbenzimidazole is noticed in the presence and absence of phase transfer catalysts such as PEG-400 and TEBAC. The 1:4 ratio of anhydrous K2CO3 to PEG-400 results in easy catalyst handling, mild reaction conditions, and excellent yields when reactions are carried out at 10-15oC. The method's simplicity makes it appealing for making N-fused heterocyclic compounds that could be used as biological replacements.
