Abstract: The title compound, C19H16N2O4, is of interest as a precursor to biologically active substituted quinolines and related compounds. The dihedral angle between the naphthalene ring system and the benzene ring is 81.9 (1)°. The crystal structure is stabilized by N-H
O intermolecular hydrogen bonds, linking the molecules into pairs around a center of symmetry. The crystal structure is further stabilized by intermolecular O-H
O hydrogen bonds, which link the molecules into chains running along a axis. An intramolecular C-H
O short contact is also present.
