Abstract
The title compound, C(16)H(15)NO(6), crystallizes with two symmetry-independent mol-ecules in the asymmetric unit. The crystal structure is stabilized by inter-molecular C-H⋯O and N-H⋯O hydrogen bonds, and intra-molecular C-H⋯O hydrogen bonds. In addition, the crystal structure exhibits two inter-molecular C-H⋯π inter-actions.
