  • Description: <jats:title>Abstract</jats:title><jats:p>The synthesis of N‐pyridinylamides has been realized by particularly efficient technologies via bimetallic organic (Co/Fe‐MOF) catalyzed oxidative amidation between 2‐aminopyridine and benzaldehyde. The C−N bond was formed with the presence of a catalyst (Co/Fe‐MOF) as a Lewis acid and the oxidant as DTBP. The oxidative amidation reaction was conducted in 1,4‐dioxane at 120 °C with a wide range of substrates producing the corresponding amide products in good to 94 % yields. Experimental results illustrated that This accessibly offers a significant improvement over the earlier successful attempts in forming <jats:italic>N‐pyridinyl amides</jats:italic>. The Co/Fe‐MOF material was synthesized by solvothermal methods with the salt mixture of Fe(NO<jats:sub>3</jats:sub>)<jats:sub>3</jats:sub>.9H<jats:sub>2</jats:sub>O and Co(NO<jats:sub>3</jats:sub>)<jats:sub>2</jats:sub>.6H<jats:sub>2</jats:sub>O. The material was determined by modern analytic methods like X‐ray diffraction (XRD), Fourier‐transform Infrared spectroscopy (FT‐IR), Scanning Electron Microscope (SEM), and N<jats:sub>2</jats:sub> adsorption/desorption isotherms.</jats:p>
