Abstract

The title compound, C(15)H(15)NO, which was synthesized under solvent-free conditions by the reaction of acetoacetone and 2-naphthyl-amine, adopts a Z conformation about the C=C bond. The enamine-ketone fragment is approximately planar [maximum deviation = 0.026 (3) Å] and forms a dihedral angle of 39.78 (3)° with the naphthalene ring system. An intra-molecular N-H⋯O hydrogen bond is observed.
