The title compound, C14H11Cl2NO2, has been prepared by the condensation of 3,5-dichlorosalicylaldehyde and 2-amino-4-methylphenol. The asymmetric unit consists of two independent molecules, both of which are almost planar; the dihedral angle between the two benzene rings is 10.61 (8)° for one molecule and 2.46 (8)° for the other. There is an intramolecular N—H...O hydrogen bond that generates S(6) ring motifs in each molecule. In the crystal, the two independent molecules are linked by O—H...O and C—H...Cl hydrogen bonds, forming a pseudo-inversion dimer. A π–π interaction, with a centroid–centroid distance of 3.6065 (12) Å, is also observed.
