5-Fluoro-1-(pentanoyl)pyrimidine-2,4(1H,3H)-dione

H.-J. Lehmler and S. Parkin

Abstract: The pentanoyl group and the 5-fluorouracil moiety of the title compound, C₉H₁₁FN₂O₃, 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-HO hydrogen bonds generate an intermolecular R₂²(8) ring. In addition, there are intra- and intermolecular C-HO interactions.
