The present invention relates to the development of novel N-(4-fluorophenyl)-5-phenyl- [1,2,4]triazolo[1,5-a]pyridine-2-carboxamide derivatives for their different pharmacological activities. It particularly relates to the development of N-(4-fluorophenyl)-5-phenyl- [1,2,4]triazolo[1,5-a]pyridine-2-carboxamide derivatives as antiviral, anticancer, antifungal, hypoglycemic, anti-tubercular, sedative, anti-type 2 diabetes activity. It specifically relates to the N-(4-fluorophenyl)-5-phenyl-[1,2,4]triazolo[1,5-a]pyridine-2-carboxamide derivatives for treatment of H37Rv and multidrug-resistant (MDR) strains of Mycobacterium tuberculosis (MTB). The present invention also relates to the process for synthesis of N-(4-fluorophenyl)- 5-phenyl-[1,2,4]triazolo[1,5-a]pyridine-2-carboxamide derivatives. The invention further relates to method for treatment of method for treatment of diseases such as tuberculosis, type 2 diabetes, bacterial, viral and fungal infections. Invention addresses the challenges in working with chemical processes and products by inventing novel reaction methodology that can maximize the desired products and minimize by-products, designing new synthetic schemes that can simplify operations in chemical productions and seeking nontoxic reagent that are inherently environmentally and ecologically benign. Synthesis of novel N-(4- fluorophenyl)-5-phenyl-[1,2,4]triazolo[1,5-a]pyridine-2-carboxamide derivatives is being employed to develop a novel synthetic methodology and their pharmacological applications. Novel series of N-(4-fluorophenyl)-5-phenyl-[1,2,4]triazolo[l,5-a]pyridine-2-carboxamide derivatives were designed synthesized evaluated for their in vitro anti-mycobacterial activity against H37Rv and multi-drug-resistant (MDR) strains of mycobacterium tuberculosis (MTB). All the synthesized compounds were characterized by spectroscopic methods like Mass, NMR and elemental analysis.

A method for the preparation of aryl and heteroaryl sulfonamides using 2,4,6-trichlorophenyl chlorosulfate (TCPC) is described. The reaction of 2-pyridylzinc reagents with TCPC resulted in 2,4,6-trichlorophenyl (TCP) pyridine-2-sulfonates, and the parent pyridine-2-sulfonate was shown to react with amines. Less electron-rich aryl- and heteroarylzinc reagents reacted with TCPC to afford sulfonyl chlorides that were converted in situ to sulfonamides.
