The title compound, C 18 H 18 N 2 O 5 , was synthesized from 2,3dimethoxyphenylmethylidenemalononitrile and ethyl acetoacetate in the presence of triethylbenzylammonium chloride in an aqueous medium. The pyridone and benzene rings make a dihedral angle of 63.8 (1) . There are intermolecular C-HÁ Á Á
