The structure of the title compound, C(13)H(17)NO, features an anti disposition of the N-H and carbonyl groups. The amide group is twisted with respect to the benzene ring [N-C(=O)-C-C torsion angle = -30.8 (4)°]. In the crystal, C(4) chains propagating in [100] are formed by inter-molecular N-H⋯O hydrogen bonds. Weak C-H⋯π inter-actions link the chains into sheets.
