The 3-methyl-butanoyl group and the 5-fluoro-uracil unit of the title compound, C9H11FN2O3, are essentially coplanar, with the carbonyl group oriented towards the ring CH group and away from the nearer ring carbonyl group. The 3-methyl-butanoyl (C=)C - N - C=O torsion angle of 9.6 (2)° is comparable to that in structurally related compounds. In the solid state, two inversion-related mol-ecules form N - H⋯O hydrogen bonds to generate an inter-molecular R 2 2(8) ring. The crystal structure also diplays intra- and inter-molecular C - H⋯O inter-actions.
