In the title compound, C₁₀H₁₇NO₃, the five-membered ring is in a slightly twisted envelope conformation. The carbonyl group is disordered over two sites on the five-membered ring, with refined occupancies of 0.906 (4) and 0.094 (4). In the crystal, molecules are linkedviaN—H...O hydrogen bonds formingC(4) chains along [001].
