In the title compound, C(15)H(15)NO, the C-N-C(O)-C amide unit is planar (r.m.s. deviation = 0.003 Å) and subtends dihedral angles of 44.71 (5) and 43.33 (5)° with the two o-tolyl rings. These aromatic rings are inclined at 4.94 (7)° to one another. The ortho-methyl groups of the two tolyl rings are anti to one another. In the crystal structure, N-H⋯O hydrogen bonds augmented by C-H⋯π inter-actions link the mol-ecules in a head-to-head fashion into chains along a. Independent chains pack in a herringbone pattern along c.
