The title mol-ecule, C(22)H(24)F(6)N(2)O(3), adopts a folded conformation whereby the carboxyl-ate residue lies over the quinolinyl residue, with the dihedral angle between the carbamate and quinoline planes being 41.64 (7)°. Helical supra-molecular C(7) chains sustained by O-H⋯O hydrogen bonds propagating along the a-axis direction feature in the crystal packing. The F atoms of one of the CF(3) groups are disordered over two orientations; the major component has a site occupancy of 0.824 (7).

The reaction of (E)-tert-butyl 4-[3-(dimethyl-amino)acrylo-yl]piperidine-1-carboxyl-ate with methyl-hydrazine leads to the formation of the title compound, C(14)H(23)N(3)O(2), with a 1-methyl-1H-pyrazol-5-yl substituent. The plane of the pyrazole ring forms a dihedral angle of 33.4 (1)° with the approximate mirror plane of the piperidine ring.
