Butyl 2-(5-bromo-3-methyl­sulfinyl-1-benzofuran-2-yl)acetate

In the title compound, C(15)H(17)BrO(4)S, the methyl­sulfinyl O atom and the methyl substituents lie on opposite sides of the plane through the benzofuran fragment. The crystal structure is stabilized by π–π inter­actions between the benzene rings of neighbouring mol­ecules [centroid–centroid distance = 3.698 (4) Å], and by C—H⋯π inter­actions between a methyl­ene H atom of the butyl group and the benzene ring of the benzofuran system. Additionally, the crystal structure exhibits weak inter­molecular C—H⋯O contacts. The butyl group is disordered over two positions, with site-occupancy factors, from refinement, of 0.720 (8) and 0.280 (8).
