5-Isopropyl-2-methyl-3-phenyl­sulfonyl-1-benzofuran

The title compound, C(18)H(18)O(3)S, was prepared by the oxidation of 5-isopropyl-2-methyl-3-phenyl­sulfanyl-1-benzofuran with 3-chloro­peroxy­benzoic acid. The phenyl ring makes a dihedral angle of 79.37 (6)° with the plane of the benzofuran fragment. The crystal structure is stabilized by aromatic π–π stacking inter­actions between the benzene and furan rings of neighbouring mol­ecules [centroid–centroid distance = 3.762 (3) Å]. In addition, the stacked mol­ecules exhibit C—H⋯π and intra­molecular C—H⋯O inter­actions.
