In the title compound, C 17 H 12 Cl 2 N 2 O 2 , the dihedral angle formed between the dichlorobenzene and pyrazolyl rings is 38.3 (3) , that between the phenyl and pyrazolyl rings is 46.8 (3) , and that between the two benzene rings is 69.4 (3) .
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.
