2-[(3R,6R)-6-Methyl-2,5-dioxomorph-olin-3-yl]-N-(propan-2-yl)acetamide.

The molecular conformation of the title compound, C(10)H(16)N(2)O(4), is determined by an intra-molecular N-H⋯O hydrogen bond involving the morpholine NH group and the amide O atom. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into chains along the a-axis direction.
