Abstract: In the title compound, C15H15NO2, the dihedral angle between the aromatic rings is 5.86 (6)°, and an intramolecular N-HO hydrogen bond generates an S(6) motif, which helps to stabilize the enamine-keto tautomer. An intramolecular O-HO hydrogen bond also occurs. In the crystal, inversion dimers linked by pairs of O-HO hydrogen bonds generate R22(10) loops. A C-HO interaction links the dimers into  chains and aromatic - stacking [centroid-centroid separation = 3.6131 (9) Å] also occurs.
