The six-membered ring in the title compound, C~10~H~17~NO~4~, has a half-chair conformation and lies to one side of the central chromophore. Molecules are connected into a supramolecular chain __via__ N—H...O hydrogen-bonding interactions and these are consolidated into a three-dimensional structure
