The molecule of the title chalcone derivative, C19H15NO, exists in a trans configuration Sugar with respect to the C=C double bond.The molecule is slightly twisted with a dihedral angle of 6.12 (12)° between the benzene ring and the naphthalene ring system.The prop-2-en-1-one bridge is nearly planar, with an r.

m.s.deviation of 0.0194 (2), and makes dihedral angles of 8.

05 (19) and 11.47 (18)° with the benzene ring and the naphthalene ring system, respectively.In the crystal, molecules are linked Wooden Flower by N—H.O hydrogen bonds into chains along the b axis.

Weak N—H.π and C—H.π interactions and a short N.O contact [2.
