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

The title compound, C(17)H(16)O(2)S, was prepared by the oxidation of 2,5,7-trimethyl-3-phenyl­sulfanyl-1-benzofuran with 3-chloro­peroxy­benzoic acid. The O atom and the phenyl group of the phenyl­sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The phenyl ring is nearly perpendicular to the plane of the benzofuran unit [88.30 (9)°] and is tilted slightly towards it. No π–π or C—H⋯π inter­actions are observed between neighbouring mol­ecules in the crystal structure because of steric hindrance induced by the three methyl groups.
