چکیده
The title compound, C(17)H(16)ClNO, was synthesized using a solvent-free method by reaction of 4-(dimethyl-amino)benzaldehyde with 4-chloro-acetophenone and NaOH. The chloro-phenyl ring makes a dihedral angle of 18.1 (3)° with the central propenone unit, while the (dimethyl-amino)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.
