In the title compound, C(21)H(17)ClFN(3)O(2), the 1H-pyrazole ring makes dihedral angles of 36.73 (7), 18.73 (7) and 60.88 (8)°, respectively, with the mean planes of the chloro-phenyl, 4-oxo-piperidine and fluoro-phenyl rings. The mol-ecular structure is stabilized by an intra-molecular C-H⋯N hydrogen bond, which forms an S(6) ring motif. In the crystal, inter-molecular C-H⋯O hydrogen bonds link mol-ecules into chains along . In addition, inter-molecular C-H⋯F hydrogen bonds with an R(2) (1)(7) ring motif connect neighbouring chains into layers parallel to the ac plane.
