The asymmetric unit of the title compound, C(17)H(17)ClN(2)O(2), contains one half-mol-ecule with a center of symmetry at the mid-point of the central C-C bond. The dihedral angle between the benzene ring and the adjacent NH-C(O)-CH(2) group is 39.9 (1)°. The methyl and Cl groups are disordered with respect to the para-positions of the benzene ring, with site-occupation factors of 0.5 each. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains parallel to the baxis.
