In the title acrylonitrile derivative, C17H14N2OS, the central aminoacrylaldehyde O=C—C=C—NH unit, wherein an intramolecular N—H⋯O hydrogen bond generates an S(6) ring motif, is approximately planar, with an r.m.s. deviation of 0.0234 (2) Å for the five non-H atoms. This plane makes dihedral angles of 41.04 (9) and 84.86 (10)° with the two phenyl rings. The dihedral angle between the two phenyl rings is 54.82 (10)°. An intramolecular C—H⋯N hydrogen bond is also present. In the crystal, weak C—H⋯π and π–π interactions, with a centroid–centroid distance of 3.8526 (14) Å, are observed.
