A simple one pot synthesis has been developed for the synthesis 1,4-dihydropyridine using an efficient and reusable silica supported MgO solid catalyst by condensation of dimedone, ethyl acetoacetate, aldehyde and ammonium acetate in methanol as a solvent at room temperature. The reactions could be carried out under mild reaction conditions with very good yield of polyhydroquinoline, up to 92%. This catalyst could be recycled very easily, which makes this methodology environmentally benign.
