An L-shaped conformation is found in the title mol-ecule, C(20)H(20)F(6)N(2)O, the C-C-C-C torsion angle linking the two fused-ring systems being -92.80?(19)°. The oxazole ring adopts an envelope conformation [the N atom lies 0.579?(2)?Å out of the plane defined by the remaining atoms], and the piperidine ring has a chair conformation. Supra-molecular chains are found in the crystal structure that are sustained by C-H?? and ?-? [3.6089?(10)?Å] inter-actions.
