The title compound, C17H16ClNO, was synthesized using a solvent-free method by reaction of 4-(dimethylamino)benzaldehyde with 4-chloroacetophenone and NaOH.The chlorophenyl ring makes a dihedral angle of 100w products 18.1 (3)° with the central propenone 12n/1200 wella unit, while the (dimethylamino)phenyl group is disordered over two orientations of equal occupancies, which make dihedral angles with the central propenone unit of 32.9 (3) and 57.4 (3)°, respectively.
