The title compound, C(18)H(19)N(3)O, displays an E conformation with respect to the C=N double bond. The dihedral angle between the mean planes of the two benzene rings is 24.49 (3)°. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring. In the crystal, mol-ecules are linked by nonclassical inter-molecular C-H⋯O hydrogen bonds to form an infinite one-dimensional chain along [010], generating a C(8) motif.
