In the title compound, C23H17Cl2F3N2O3, the molecular conformation is significantly strained: atoms O, C(=O) and C attached to the central benzene ring deviate from its plane by 0.118 (2), 0.139 (2) and 0.174 (2) Å, respectively. In the crystal, weak C—H⋯O interactions link the molecules into chains along . The crystal packing exhibits short intermolecular Cl⋯F [2.9840 (16) Å] and Cl⋯Cl [3.2957 (12) Å] contacts.
