The NH unit on the exocyclic C C double bond in the title compound, C 24 H 21 N 3 O, which is on the same side of the double bond as the C O unit of the pyrazolone ring, interacts with the carbonyl group through an intramolecular N-HÁ Á ÁO hydrogen bond [2.685 (2) A ˚].
The title compound 3 was obtained during the rearrangement of isoxazol-5-yl hydrazine 1 to 1 -aminopyrazolone 2 at \(115^{\circ}\). X-ray analysis of the corresponding benzylidene derivative allowed us to achieve the structure assignment.
