5-Fluoro-2-methyl-3-(4-methyl-phenyl-sulfon-yl)-1-benzofuran.

In the title compound, C(16)H(13)FO(3)S, the 4-methyl-phenyl ring makes a dihedral angle of 76.04 (4)° with the mean plane of the benzofuran fragment. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, and by a slipped π-π inter-action between the furan and benzene rings of adjacent mol-ecules [centroid-centroid distance = 3.780 (2) Å, inter-planar distance = 3.475 (2) Å and slippage = 1.488 (2) Å].
