title: 5-Cyclo-pentyl-2-methyl-3-(4-methyl-phenyl-sulfon-yl)-1-benzo-furan.
abstract: In the title compound, C21H22O3S, the cyclo-pentyl ring adopts a twist conformation. The dihedral angle between the mean planes of the benzo-furan and 4-methyl-phenyl rings is 72.38 (6)°. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯π inter-actions, forming a three-dimensional supra-molecular network.
