In the title compound, C 19 H 15 Cl 4 NO 3 , the isoindole unit is planar and the oxazino ring adopts a twist-boat conformation. The dihedral angle between the isoindole unit and the phenyl ring is 50.46 (13) . The molecules are linked via intermolecular O-HÁ Á ÁO hydrogen bonds and weak C-HÁ Á ÁO a
