title: Ethyl 2-(5-fluoro-3-methyl-sulfinyl-1-benzofuran-2-yl)acetate.
abstract: In the title compound, C(13)H(13)FO(4)S, the O atom and the methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane through the benzofuran fragment. The crystal structure exhibits four inter-molecular non-classical C-H⋯O hydrogen bonds. In addition, the crystal structure contains aromatic π-π inter-actions between the furan and benzene rings of adjacent mol-ecules [centroid-centroid distance = 3.743 (2) Å], and two inter-molecular C-H⋯π inter-actions.
