The asymmetric unit of the title compound, C(12)H(16)ClNO(4), contains two crystallographically independent mol-ecules. The benzene rings of the two independent mol-ecules are oriented at a dihedral angle of 88.50 (3)°. Intra-molecular 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, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains along the a axis.
标题化合物C(12)H(16)ClNO(4)的不对称单元包含两个晶体学独立的分子。两个独立分子的苯环以88.50 (3)°的二面角取向。每个分子中涉及甲氧基苯甲酸酯羰基的分子内N-H⋯O氢键导致形成两个平面六元环,相对于相邻苯环的二面角分别为1.39 (3)°和0.68 (3)°。在晶体结构中,分子间N-H⋯O氢键将分子沿a轴连接成链。
