In the title compound, the 1,2,3,4-tetrahydropyridine ring of the quinoline moiety adopts a half-chair conformation while the pyrrolidine ring has an envelope conformation. In the crystal, molecules are linked by N—HO and C—HO hydrogen bonds, forming sheets lying parallel to (10), which are linked via C—HF hydrogen bonds and C—Hπ interactions, forming a three-dimensional structure.

In the title compound, C13H14N2O2, the C5 ring has an envelope conformation with the C atom adjacent to the quaternary C being the flap. The five atoms comprising the imidazolidine-2,4-dione ring are almost planar (r.m.s. deviation = 0.004 Å). The dihedral angle between the five-membered rings is 89.66 (10)°. In the crystal, inversion-related molecules are connected via {HNCO}2 synthons. These are linked into a helical supramolecular chain along [010] by C—HO interactions.
