چکیده	1-Methyl imidazole-based ionic liquid-stabilized silica-coated Fe3O4 magnetic nanoparticles [Fe3O4@SiO2@(CH2)3-1-methyl imidazole]HSO4 as a solid acid magnetic nanocatalyst was explored in the synthesis of pyrano[2,3-d]pyrimidine derivatives. Pyrano[2,3-d]pyrimidine derivatives were synthesized by a highly efficient three-component reaction of various benzaldehydes, malononitrile, and barbituric acid. The catalyst was characterized by using various analysis techniques such as Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), differential scanning calorimetry-thermogravimetry analysis (DSC-TGA), scanning electron microscopy (SEM), and vibrating sample magnetometry (VSM).
