The title compound, C14H13NO4, was prepared through a palladium-catalysed Suzuki–Miyaura coupling reaction. The asymmetric unit comprises two molecules related by pseudo-inversion symmetry. The dihedral angles between the benzene rings in the two molecules are 44.30 (6) and 48.50 (6)° while those between the benzene ring and the nitro group are 6.54 (13) and 5.73 (10)°. The crystal packing is defined only by Van der Waals interactions.
