The asymmetric unit of the title compound, C(19)H(14)O(3), contains two crystallographically independent mol-ecules in which the dihedral angles between the naphthalene and benzofuran ring systems are 76.49 (7) and 86.17 (7)°. In the crystal, mol-ecules are linked by inter-molecular C-H⋯O hydrogen-bonding inter-actions into chains running parallel to the a axis. In addition, the crystal packing is stabilized by C-H⋯π inter-actions.
