Summary:In the title molecule, C20H18N4O2, the dihedral angles between the central benzene ring and the two pyridine rings are 12.07 (8) and 4.80 (1)°, and that between the two pyridine rings is 16.78 (9)°. An intramolecular N—H...O hydrogen bond may influence the molecular conformation. In the crystal structure, intermolecular N—H...O hydrogen bonds link molecules into centrosymmetric dimers, while weak intermolecuar C—H...O hydrogen bonds link these dimers into one‐dimensional chains.
