5-Cyclo-pentyl-2-(3-fluoro-phen-yl)-3-methyl-sulfinyl-1-benzofuran.
In the title compound, C(20)H(19)FO(2)S, the benzofuran fragment is essentially planar, with a largest deviation from the mean plane of 0.026 (2) Å. The benzene ring makes a dihedral angle of 30.72 (12)° with this plane. The cyclo-pentyl group adopts an envelope conformation, with the α-C atom as the flap. This atom is disordered over two sites with occupancy factors of 0.803 (16) and 0.197 (16). In the crystal, mol-ecules are linked by weak C-H⋯O, C-H⋯π and C-F⋯π [3.257 (3) Å] inter-actions.
