In the title compound, C14H17FN2O, the 1,2,3,4-tetra-hydro-pyridine ring of the quinoline moiety adopts a half-chair conformation, while the pyrrolidine ring has an envelope conformation with the central methyl-ene C atom as the flap. The pyrrolidine ring lies in the equatorial plane and its mean plane is normal to the mean plane of the quinoline ring system, with a dihedral angle value of 88.37 (9)°. The bridging N-C bond distance [1.349 (3) Å] is substanti-ally shorter than the sum of the covalent radii (d cov: C-N = 1.47 Å and C=N = 1.27 Å), which indicates partial double-bond character for this bond, resulting in a certain degree of charge delocalization. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds, forming sheets lying parallel to (10-1). These two-dimensional networks are linked via C-H⋯F hydrogen bonds and C-H⋯π inter-actions, forming a three-dimensional structure.
