Abstract

The asymmetric unit of the title compound, C12H16ClNO4, contains two crystallographically independent mol­ecules. The benzene rings of the two independent mol­ecules are oriented at a dihedral angle of 88.50 (3)°. Intra­molecular N—H⋯O hydrogen bonds involving the methoxybenzoate carbonyl group in each molecule result in the formation of two planar, six-membered rings, oriented at dihedral angles of 1.39 (3) and 0.68 (3)° with respect to the adjacent benzene rings. In the crystal structure, inter­molecular N—H⋯O hydrogen bonds link the mol­ecules into chains along the a axis.
