In the title molecule, C18H16ClN3O2, the seven-membered ring adopts an envelope conformation with the flap atom deviating by 0.801 (5) Å from the mean plane formed by the remaining non-H atoms. Intermolecular N—H⋯O hydrogen bonds link the molecules into centrosymmetric dimers. The crystal packing also exhibits weak intermolecular C—H⋯N hydrogen bonds and π–π interactions with a short distance of 3.734 (3) Å between the centroids of the aromatic rings of neighbouring molecules.
