In this research, the synthesis of pyrido[2,3‐d:5,6‐d′]dipyrimidines by CuFe2O4/KCC‐1/PMA magnetic nanoparticles was reported. Synthesis of pyrido[2,3‐d:5,6‐d′]dipyrimidines was performed under solvent‐free conditions with good to excellent yields. The prepared nanocatalyst was synthesized in three steps and also was characterized by Fourier transform infrared (FT‐IR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy‐dispersive X‐ray spectroscopy (EDX), X‐ray diffraction (XRD), vibrating sample magnetometry (VSM), and N2 adsorption–desorption measurement (Brunauer–Emmett–Teller [BET]) analyses. In addition, the reusability studies of CuFe2O4/KCC‐1/PMA showed that the recovered catalyst could be used for several times.
