The title compound, C21H19ClN2O3, was synthesized by the reaction of 4-chlorobenzaldehyde, 4-methoxyacetophenone, ethyl cyanoacetate and ammonium acetate under microwave irradiation. X-ray analysis reveals that the benzene rings are orthogonal to each other and form dihedral angles of 29.34 (6) and 79.45 (6)° with the pyridine ring. In the solid state, the molecules exist as centrosymmetric N—H…O hydrogen-bonded dimers.
