Abstract

In the title compound, C20H20O2S, the cyclo­pentyl ring adopts an envelope conformation with the flap atom connected to the benzofuran residue. The phenyl ring makes a dihedral angle of 32.36 (9)° with the mean plane of the benzofuran fragment. In the crystal, mol­ecules are linked through weak C—H⋯O inter­actions. In the cyclo­pentyl ring, two adjacent C atoms are disordered over two sets of sites with site occupancy factors of 0.675 (8) and 0.325 (8).
