In the title compound, C15H15NO2, the dihedral angle between the aromatic rings is 5.86 (6)°, and an intra-molecular N-H⋯O hydrogen bond generates an S(6) motif, which helps to stabilize the enamine-keto tautomer. An intra-molecular O-H⋯O hydrogen bond also occurs. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (2)(10) loops. A C-H⋯O inter-action links the dimers into [010] chains and aromatic π-π stacking [centroid-centroid separation = 3.6131 (9) Å] also occurs.
在标题化合物C₁₅H₁₅NO₂中，芳环之间的二面角为5.86 (6)°，分子内N-H⋯O氢键生成一个S(6)基序，有助于稳定烯胺-酮互变异构体。还存在分子内O-H⋯O氢键。在晶体中，通过O-H⋯O氢键对连接的反演二聚体生成R₂²(10)环。C-H⋯O相互作用将二聚体连接成[010]链，并且还存在芳族π-π堆积[质心-质心间距 = 3.6131 (9) Å]。
