In the title compound, C 18 H 16 Cl 2 O 4 , the mean planes of the 2,4‐dichlorophenyl and 2,3,4‐trimethoxyphenyl groups have a dihedral angle of 55.2 (2)°. The torsion angle connecting the ketone O atom of the prop‐2‐ene group to the 2,4‐dichlorophenyl group is 57.3 (2)°. The crystal packing is stabilized by intermolecular C—H...O hydrogen bonding between a methoxy H atom and the ketone O atom in the prop‐2‐ene group, which links the molecules into chains in an alternate inverted pattern obliquely parallel to the ac face and diagonal along the a axis of the unit cell.
