In the title compound, C18H16N4O2, the dihedral angle between the fused tricyclic ring system and the pendant benzene ring is 11.03 (4)°. The C—O—C—C torsion angle in the ethyl ester is 102.97 (12)°. The molecular conformation is supported by intramolecular C—H...N and C—H...O hydrogen bonds, which close S(6) and S(7) rings, respectively. Aromatic π–π stacking is observed in the crystal [shortest centroid–centroid separation = 3.5274 (7) Å].
