In the title compound, C(18)H(17)N(3)O, the dihedral angle between the phenyl and benzene rings is 11.22 (14)°. Apart from the methyl H atoms, the mol-ecule is close to planar, with a maximum deviation of 0.145 (3) Å. Intra-molecular C-H⋯O and C-H⋯N inter-actions occur. In the crystal, inversion dimers linked by pairs of N-H⋯N hydrogen bonds occur, resulting in an R(2) (2)(12) ring motif. Further C-H⋯N and C-H⋯O bonds generate R(1) (2)(7) and R(2) (2)(22) motifs and a C-H⋯π inter-action also occurs.
