In the title compound, C(15)H(12)Cl(2)N(2)O(3)·CH(3)OH, the Schiff base mol-ecule is nearly planar, with a dihedral angle of 4.5 (2)° between the two benzene rings. An intra-molecular O-H⋯N hydrogen bond is observed. The methanol solvent mol-ecule is linked to the Schiff base mol-ecule through inter-molecular N-H⋯O and O-H⋯O hydrogen bonds.
