Mol-ecules of title compound, C(16)H(20)O(4)S, which was synthesized by the oxidation of isopropyl 2-(4,6-dimethyl-3-methyl-sulfanyl-1-benzofuran-2-yl)acetate, inter-act through C-H⋯π inter-actions between a methyl-ene H atom and the aromatic carbon ring of the benzofuran ring system, and by C-H⋯O hydrogen bonds. Adjacent stacked mol-ecules exhibit a carbon-yl-carbonyl inter-action [3.295 (2) Å]. The O atom of the methyl-sulfinyl group is disordered over two positions with site-occupancy factors of 0.9 and 0.1.
标题化合物C(16)H(20)O(4)S由2-(4,6-二甲基-3-甲基硫基-1-苯并呋喃-2-基)乙酸异丙酯氧化合成，其分子通过亚甲基H原子与苯并呋喃环系统的芳碳环之间的C-H⋯π相互作用以及C-H⋯O氢键相互作用。相邻的堆积分子表现出羰基-羰基相互作用[3.295 (2) Å]。甲亚砜基的O原子在两个位置上无序，占位因子分别为0.9和0.1。
