Experimental

R factor = 0.045; wR factor = 0.089; data-to-parameter ratio = 17.3. In the title compound, C17H15BrO2S, the 4-methylbenzene ring makes a dihedral angle of 89.01 (7) with the mean plane [r.m.s. deviation = 0.013 (2) Å] of the benzofuran fragment. In the crystal, molecules are linked into supramolecular layers that stack along [001] by weak C—H O, C—H and C— S [3.364 (2) Å] interactions.
