In the title compound, C18H18N2O, the morpholine ring adopts a chair conformation with the exocyclic N-C bond in an equatorial orientation. The dihedral angles between the central benzene ring and the morpholine ring (all atoms) and the cyano-benzene ring are 87.87 (7) and 52.54 (7)°, respectively. No significant inter-molecular inter-actions are observed in the crystal structure.
