Abstract: In the title compound, C17H16N4O4, the dihedral angle between the planar nine-membered bicyclic ring system and the benzene ring is 81.9 (1)°. Intramolecular N-H...O and intermolecular N-H...O, N-H...N and C-H...N hydrogen bonds are effective in stabilizing the molecular and crystal structure.
