Abstract

The penta­noyl group and the 5-fluoro­uracil moiety of the title compound, C 9 H 11 FN 2 O 3 , are essentially coplanar, with the penta­noyl carbonyl group oriented towards the ring CH group and away from the nearer ring carbonyl group. In the crystal structure, two inversion-related mol­ecules form a dimer structure, in which two N—H⋯O hydrogen bonds generate an inter­molecular R 2 2 (8) ring. In addition, there are intra- and inter­molecular C—H⋯O inter­actions.
