✦ Synopsis

Geometric parameters of the title compound, C~17~H~16~ClNO~3~, are in the usual ranges. The two aromatic rings are almost perpendicular, with a dihedral angle of 89.26 (5)°. The carboxyl group is coplanar with the aromatic ring to which it is attached [dihedral angle = 1.70 (17)°]. The packing involves inversion-symmetric dimers bridged via hydrogen bonding of the carboxyl groups. In addition, there is an N—H...O hydrogen bond between the amino group and the carbonyl O atom.
