Abstract
Molecules of title compound, C16H20O4S, which was synthesized by the oxidation of isopropyl 2-(4,6-dimethyl-3-methylsulfanyl-1-benzofuran-2-yl)acetate, interact through C—H⋯π interactions between a methylene H atom and the aromatic carbon ring of the benzofuran ring system, and by C—H⋯O hydrogen bonds. Adjacent stacked molecules exhibit a carbonyl–carbonyl interaction [3.295 (2) Å]. The O atom of the methylsulfinyl group is disordered over two positions with site-occupancy factors of 0.9 and 0.1.
