2-Chloro-ethyl 2-(5-bromo-3-methyl-sulfinyl-1-benzofuran-2-yl)acetate.

ABSTRACT: In the title compound, C(13)H(12)BrClO(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. There is a mean deviation of 0.016 (4) Å from the least-squares plane defined by the nine constituent benzofuran atoms. The crystal structure is stabilized by aromatic π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.689 (7) Å]and by a weak C-H⋯π interaction between an H atom of the methylene group bonded to the carboxylate O atom and the benzene ring of an adjacent molecule. In addition, the crystal structure exhibits weak non-classical inter-molecular C-H⋯O hydrogen bonds. The chloro-ethyl group is disordered over two positions, with refined site-occupancy factors
