The asymmetric unit of the title compound, C17H19N3O3·CH4O, comprises two Schiff base molecules and two methanol solvent molecules. The Schiff base molecules are approximately planar, with r.m.s. deviations from the planes defined by the non-H atoms of 0.107 and 0.154 Å, and with dihedral angles between the benzene rings of 4.49 (15) and 8.39 (15)°, respectively. This near-planarity is assisted by the formation of intramolecular O—H⋯N hydrogen bonds in each molecule. In the crystal, the components are linked by N—H⋯O and O—H⋯O hydrogen bonds to form chains along [010].
