The title compound, C16H15NO4, exhibits two near-planar aromatic ester groups with a maximum aryl-ester torsion angle of 1.9 (2)°. The dihedral angle between the benzene rings is 44.7 (1)°. In the crystal, N-HO hydrogen bonding is observed along with C-HO contacts, forming chanins along . No - interactions were noted between the benzene rings.
