4-(3,3-Dimethyl­perhydro-1,3-oxa­zolo[3,4-a]pyridin-1-yl)-2,8-bis­(tri­fluoro­meth­yl)quinoline

An L-shaped conformation is found in the title mol­ecule, 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. Supra­molecular chains are found in the crystal structure that are sustained by C—H⋯π and π–π [3.6089 (10) Å] inter­actions.
