2,5,7-Trimethyl-3-(4-methyl-phenyl-sulfon-yl)-1-benzofuran.
In the title compound, C(18)H(18)O(3)S, the 4-methyl-phenyl ring makes a dihedral angle of 86.35 (3)° with the mean plane [mean deviation = 0.006 (1) Å] of the benzofuran fragment. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions. The crystal structure also exhibits weak π-π inter-actions between the furan and benzene rings of neighbouring benzofuran systems [centroid-centroid distance = 3.685 (2), inter-planar distance = 3.572 (2) and slippage = 0.906 (2) Å].
