Abstract: In the asymmetric unit of the title compound, C₁₇H₁₉NO₃, there are three independent molecules, which are align nearly parallel to each other and adopt the phenol-imine tautomeric form. In each molecule, an intramolecular O-HN hydrogen bond results in the formation of an S(6) ring motif. The dihedral angles between the aromatic rings in the three independent molecules are 13.55 (2), 21.24 (2) and 46.26 (1)°. C-H [pi] interactions are also observed in the crystal structure.
