title: 4-(2,3-Dimethyl-anilino)pent-3-en-2-one.
abstract: In the title compound, C(13)H(17)NO, the dihedral angle between the aryl ring and the amino-acryl-aldehyde mean plane [N-C=C-C=O; maximum deviation = 0.0144 (9) Å] is 53.43 (4)°. There is an intra-molecular N-H⋯O hydrogen bond involving the amine and carbonyl groups. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming chains propagating along [001].
