4-(2,3-Dimethylanilino)pent-3-en-2-one

Abstract

In the title compound, C13H17NO, the dihedral angle between the aryl ring and the aminoacrylaldehyde mean plane [N—C=C—C=O; maximum deviation = 0.0144 (9) Å] is 53.43 (4)°. There is an intramolecular N—H...O hydrogen bond involving the amine and carbonyl groups. In the crystal, molecules are linked by C—H...O hydrogen bonds, forming chains propagating along [001].
