The asymmetric unit of the title compound, C22H18N2O2, contains two crystallographically independent mol-ecules, in which each mol-ecule is composed of three planar six-membered rings and one nonplanar seven-membered ring. The six-membered A (phenol), B (fused benzene) and C (methoxyphenyl) rings are oriented with respect to each other at dihedral angles of 88.79 (3) (A/B), 68.16 (3) (A/C) and 37.51 (2)° (B/C), and 82.43 (3) (A′/B′), 78.52 (2) (A′/C′) and 28.65 (3)° (B′/C′). The seven-membered rings adopt near-boat conformations. Intra-molecular O - H⋯N and C - H⋯O hydrogen bonds are present in the crystal structure.
