【 摘 要 】

In the title compound, C21H20N2O3, the planes of the benzene ring and the naphthalene ring system are inclined to one another by 70.95°, and by 4.99 (6) and 75.93 (5)°, respectively, to the mean plane of the pyrazoline ring. The latter has an envelope conformation with the methine (CH) C atom as the flap. There is an intra­molecular O—H⋯N hydrogen bond that forms an S(6) ring motif. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds, forming chains along [100]. The chains are linked via C—H⋯N hydrogen bonds, forming sheets parallel to the ab plane. The sheets are linked by a series of N—H⋯π and C—H⋯π inter­actions forming a three-dimensional structure.
