2,5,7-Trimethyl-3-phenyl­sulfonyl-1-benzofuran

The title compound, C(17)H(16)O(3)S, was prepared by the oxidation of 2,5,7-trimethyl-3-phenyl­sulfanyl-1-benzofuran with 3-chloro­peroxy­benzoic acid. The phenyl ring exhibits a dihedral angle of 81.16 (4)° with the plane of the benzofuran fragment. The crystal structure is stabilized by π–π inter­actions between the furan and benzene rings of neighbouring mol­ecules [centroid–centroid distance = 3.874 (2) Å] and by C—H⋯π inter­actions between a phenyl H atom of the phenyl­sulfonyl substituent and the furan ring of adjacent mol­ecules. In addition, the crystal structure exhibits intra- and inter­molecular C—H⋯O inter­actions.
