title: 5-Cyclo-pentyl-2-(4-fluoro-phen-yl)-3-isopropyl-sulfonyl-1-benzofuran.
abstract: In the title compound, C22H23FO3S, the cyclo-pentyl ring adopts an envelope conformation with the flap atom connected to the benzofuran residue. The 4-fluoro-phenyl ring makes a dihedral angle of 43.67 (3)° with the mean plane [r.m.s. deviation = 0.008 (1) Å] of the benzofuran fragment. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions, forming a three--dimensional network. The crystal structure also exhibits slipped π-π inter-actions between the benzene and furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.883 (2) Å and slippage = 1.731 (2) Å].
