5-Chloro-2,7-dimethyl-3-(3-methyl-phenyl-sulfon-yl)-1-benzo-furan.

ABSTRACT: In the title compound, C17H15ClO3S, the dihedral angle between the mean planes of the benzo-furan and 3-methyl-phenyl rings is 76.99?(4)°. In the crystal, mol-ecules are linked by C-H?O hydrogen bonds into chains along the b-axis direction. These chains are linked by ?-? inter-actions between the benzene and furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.976?(2)?Å].
