Abstract: In the title compound, C₁₄H₁₁ClN₂O₄·CH₃OH, the molecule adopts an E conformation about the C=N bond. The compound is in the enamine-keto form. The two terminal benzene rings make a dihedral angle of 10.53 (9)°. Intra-molecular O-HO and O-HN hydrogen bonding stabilizes the molecular structure. In the crystal, O-HO hydrogen bonds link the molecules, forming chains running along the b axis.
