In the title compound, C(13)H(13)FN(2)O(3), the fused piperidine ring is in a chair conformation. The fused pyrrolidine ring shows an envelope conformation with the N atom displaced by 0.661 (3) Å out of the plane formed by the four C atoms of the pyrrolidine ring. The dihedral angle between this plane and the plane formed by the four attached C atoms of the piperidine ring (not including the carbonyl C atom) is 67.63 (10)°. The F atom is disordered and was refined using a split model with an occupancy ratio of 0.910 (3): 0.080 (3).
