The title compound, C(17)H(16)O(3)S, was prepared by the oxidation of 5-ethyl-2-methyl-3-phenyl-sulfanyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. The phenyl ring makes a dihedral angle of 75.94 (8)° with the plane of the benzofuran fragment. The crystal structure is stabilized by π-π inter-actions between the furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.620 (4) Å]. In addition, the crystal structure exhibits C-H⋯π inter-actions.
标题化合物C(17)H(16)O(3)S是通过用3-氯过氧苯甲酸氧化5-乙基-2-甲基-3-苯基硫烷基-1-苯并呋喃制备的。苯环与苯并呋喃片段的平面形成75.94 (8)°的二面角。晶体结构通过相邻分子的呋喃环之间的π-π相互作用得以稳定[质心-质心距离 = 3.620 (4) Å]。此外，晶体结构还表现出C-H⋯π相互作用。
