In the title compound, C18H17NO4, the dihedral angle between the phenyl ring and the fused six-membered ring is 77.65 (4)°. The conformation of the molecule is determined in part by an intramolecular N—H...O hydrogen bond between the amino H atom and the carbonyl O atom, forming anS(6) motif. In the crystal, molecules are linked into N—H...O hydrogen-bonded inversion dimers which are then connected into chains along [001], forming a two-dimensional network parallel to (100)viaO—H...O hydrogen bonds. C—H...O interactions further contribute to the crystal stability. The ethyl group is disordered over two sets of sites in a 0.801 (5):0.199 (5) ratio.
