In the title compound, C17H15FO3S, the dihedral angle between the mean planes of the benzo-furan and 2-fluoro-phenyl rings is 87.61 (4) Å. In the crystal, mol-ecules are linked via pairs of C-H⋯π inter-actions into inversion-related dimers. These dimers are linked by C-H⋯O hydrogen bonds into supra-molecular chains running along the a-axis direction.
