In the mol-ecule of the title compound, C(16)H(15)NO(5), the aromatic rings are oriented at a dihedral angle of 74.89 (3)°. Intra-molecular C-H⋯O inter-actions result in the formation of a seven-membered ring. In the crystal structure, weak inter-molecular C-H⋯O inter-actions link the mol-ecules into chains along the b axis.
在标题化合物C(16)H(15)NO(5)的分子中，芳环以74.89 (3)°的二面角取向。分子内C-H⋯O相互作用导致形成一个七元环。在晶体结构中，弱的分子间C-H⋯O相互作用将分子沿b轴连接成链。
