In the title compound, C17H14N2O, the N-benzylformamide and phenyl groups are located on the opposite sides of the C=C bond, showing an E configuration; the terminal phenyl rings are twisted to each other at a dihedral angle of 63.61 (7)°. Intermolecular classical N-HN and weak C-HO hydrogen bonds occur in the crystal structure.
