title: 5-Ethyl-3-(4-Fluoro-phenyl-sulfon-yl)-2-methyl-1-benzofuran.
abstract: In the title mol-ecule, C(17)H(15)FO(3)S, the 4-fluoro-phenyl ring makes a dihedral angle of 74.06 (4)° with the mean plane of the benzofuran fragment. In the crystal structure, mol-ecules are linked by weak inter-molecular C-H⋯O and C-H⋯π inter-actions. The crystal structure also exhibits aromatic π-π inter-actions between the benzene rings of adjacent mol-ecules [centroid-centroid distance = 3.629 (2) Å].
