The structure of the title compound, C 25 H 23 N 3 O 2 , features a central pyrazole ring; an amine NH unit interacts with the ring CO unit through an intramolecular N-HÁ Á ÁO hydrogen bond [NÁ Á ÁO = 2.700 (2) A ˚]
In the title compound, C 24 H 18 F 3 N 3 O, the molecule exists in the enamine-keto tautomeric form. The pyrazolone ring makes dihedral angles of 31.8 (2), 45.4 (2) and 71.2 (2) with the 1-phenyl, aniline and methylene-bound phenyl rings, respectively. An intramolecular N-HÁ Á ÁO hydrogen bond helps
