Abstract: In the molecule of the title compound, C11H14N2O4, a bifurcated intra/intermolecular N-H
(O,O) hydrogen bond occurs.The intramolecular component results in a non-planar six-membered ring with a flattened-boat conformation. In the crystal structure, the intermolecular interaction links the molecules into chains parallel to the b axis.
