title: 4-[(2,5-Dimethyl-anilino)acet-yl]-3,4-di-hydro-quinoxalin-2(1H)-one.
abstract: In the title compound, C(18)H(19)N(3)O(2), the dihedral angle between the benzene rings is 20.47 (10)° and an intra-molecular N-H⋯O hydrogen bond occurs, generating an S(5) ring. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds lead to R(2) (2)(8) loops.
