Methyl 2-(5-fluoro-3-methyl-sulfinyl-1-benzofuran-2-yl)acetate.

ABSTRACT: In the title compound, C(12)H(11)FO(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 [O-S-C-C and C-S-C-C torsion angles = 126.70 (13) and -123.55 (13)°, respectively]. The crystal structure is stabilized by weak non-classical inter-molecular C-H⋯O hydrogen-bond inter-actions. The crystal structure also exhibits aromatic π-π stacking inter-actions between furan/benzene and benzene/benzene rings of adjacent benzofuran ring systems [centroid-centroid distances = 3.8258 (9) and 3.8794 (9) Å] and a weak inter-molecular C-H⋯π ring inter-action.
