چکیده

The title compound, C(17)H(15)BrOS, was prepared by the Lewis acid-catalysed reaction of 2,4-dimethyl-phenol with 4'-bromo-2-chloro-2-(methyl-sulfan-yl)acetophenone. The 4-bromo-phenyl ring is rotated slightly out of the benzofuran plane, making a dihedral angle of 8.4 (1)°. The crystal structure is stabilized by a CH(2)-H⋯π inter-action between the 5-methyl group and the benzene ring of the benzofuran system.

The title compound, C(13)H(14)O(3)S, was prepared by alkaline hydrolysis of ethyl 2-(5,7-dimethyl-3-methyl-sulfanyl-1-benzofuran-2-yl)acetate. In the crystal structure, the carboxyl groups are involved in inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. These dimers are further packed into stacks along the a axis by weak C-H⋯π inter-actions.
