The asymmetric unit of the title compound, C20H17NO4, consists of two crystallographically independent mol­ecules. In one of the mol­ecules, the central benzene ring forms dihedral angles of 2.26 (6) and 58.68 (6)° with the terminal benzene rings and the dihedral angle between the terminal benzene rings is 56.45 (6)°. The corresponding values for the other mol­ecule are 35.17 (6), 70.97 (6) and 69.62 (6)°, respectively. In the crystal, an inversion dimer linked by a pair of C—H⋯O hydrogen bonds occurs for one of the unique mol­ecules. C—H⋯π and π–π [centroid–centroid distances = 3.7113 (8) and 3.7216 (7) Å] inter­actions link the components into a three-dimensional network.
