In the title compound, C(21)H(17)NO, the phenyl ring directly linked to the carbonyl group is oriented at an angle of 7.3 (2)° with respect to the aniline ring, and at an angle of 55.6 (2)° with respect to the other phenyl ring. There is an intra-molecular hydrogen bond involving the NH group and the carbonyl O atom. The crystal structure is stabilized by weak C-H⋯π inter-actions, which link the mol-ecules into a herringbone arrangement.
