چکیده
In the title compound, C(18)H(19)NO, the dihedral angle between 4-methyl-phenyl and 4-(dimethyl-amino)phenyl rings is 45.5 (3)°. The C-C=C-C torsion angle of 173.8 (3)° indicates that the mol-ecule adopts an E configuration. The dimethyl-amino group is nearly coplanar with the attached benzene ring, making a dihedral angle of 2.7 (3)°. Weak inter-molecular C-H⋯π inter-actions are observed in the crystal structure.
