title: 5-Cyclo-pentyl-2-(4-fluoro-phen-yl)-3-methyl-sulfinyl-1-benzofuran.
abstract: In the title compound, C(20)H(19)FO(2)S, the cyclo-pentyl ring adopts an envelope conformation. The 4-fluoro-phenyl ring makes a dihedral angle of 27.10 (7)° with the mean plane of the benzofuran fragment. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions. In the cyclo-pentyl ring, one C atom is disordered over two orientations with site-occupancy factors of 0.617 (7) and 0.383 (7).
