5-Bromo-3-ethyl-sulfinyl-7-methyl-2-(4-methyl-phen-yl)-1-benzo-furan.
In the title compound, C18H17BrO2S, the dihedral angle between the mean planes of the benzo-furan and 4-methyl-phenyl rings is 14.54 (5)°. In the crystal, mol-ecules are linked via pairs of π-π inter-actions between the benzene and 4-methyl-phenyl rings, with centroid-centroid distances of 3.811 (3) and 3.755 (3) Å. A similar inter-action is found between the furan and 4-methyl-phenyl rings, with a centroid-centroid distance of 3.866 (3) Å between neighbouring mol-ecules. The mol-ecules are stacked along the a-axis direction. In addition, a short Br⋯O contact distance of 3.128 (2) Å is observed between inversion-related dimers.
