The asymmetric unit of the title compound, C(17)H(18)N(2)O(4), contains two independent mol-ecules (A and B) differing principally in the conformations of the alkyl chains, anti for molecule A and gauche for molecule B. The dihedral angles between the aromatic rings are 82.51 (6) and 82.25 (6)° in the two molecules. In the crystal, amide-amide inter-actions (as N-H⋯O=C) results in distinct chains of A and B mol-ecules running parallel to the a-axis direction. C-H⋯O inter-actions also occur.
标题化合物C(17)H(18)N(2)O(4)的不对称单元包含两个独立分子（A和B），主要区别在于烷基链的构象，分子A为反式，分子B为gauche式。两个分子中芳环之间的二面角分别为82.51 (6)°和82.25 (6)°。在晶体中，酰胺-酰胺相互作用（如N-H⋯O=C）导致A和B分子形成平行于a轴方向的不同链状结构。还存在C-H⋯O相互作用。
