Isopropyl 2-(5-chloro-3-methylsulfinyl-1-benzofuran-2-yl)acetate

In the title compound, C14H15ClO4S, the S atom has a distorted trigonal-pyramidal coordination. The O atom and the methyl group of the methylsulfinyl substituent lie on opposite sides of the benzofuran ring system. The crystal structure is stabilized by intermolecular aromatic pi-pi interactions between the benzene rings of neighbouring molecules [centroid-centroid distance = 4.057 (3) angstrom], and by C-H center dot center dot center dot pi interactions between a methyl H atom and the benzene ring of an adjacent molecule.
