Abstract: The asymmetric unit of the title compound, C17H17ClN2O2, contains one half-molecule with a center of inversion at the mid-point of the central C-C bond. The amide N-H group is anti to the meta-chloro/methyl groups in the adjacent benzene rings. The dihedral angle between the benzene ring and the NH-C(O)-CH2 segment is 43.5 (1)°. In the crystal, intermolecular N-HO hydrogen bonds link the molecules into chains along the a axis. The methyl group and the Cl atom occupy the same position and were treated in a disorder model with site-occupation factors of 0.5 each.
