3-(3-Chloro-phenyl-sulfin-yl)-2,4,6,7-tetra-methyl-1-benzofuran.

In the title compound, C(18)H(17)ClO(2)S, the 3-chloro-phenyl ring makes a dihedral angle of 72.62 (4)° with the mean plane of the benzofuran fragment. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O and C-H⋯π inter-actions. The crystal structure also exhibits a slipped π-π inter-action between the 3-chloro-phenyl rings of adjacent mol-ecules [centroid-centroid distance = 3.751 (2) Å, inter-planar distance = 3.450 (2) Å and slippage = 1.472 (2) Å].
