Propyl 2-(5-chloro-3-methyl-sulfinyl-1-benzofuran-2-yl)acetate

In the title compound, C(14)H(15)ClO(4)S, the O atom and the methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The crystal structure is stabilized by aromatic π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-to-centroid distance = 3.635 (3) Å], and by C-H⋯π inter-actions between a propyl methyl-ene H atom and the furan ring of an adjacent mol-ecule. In addition, the crystal structure exhibits weak inter-molecular C-H⋯O hydrogen bonds.
