Formation and Structure of 1-Amino-4-methyl-4-(4-methyl-5-phenyl1H-pyrazol-3-ylamino)-3-phenyl-4,5-dihydro- 1H-pyrazol-5-one

The title compound 3 was obtained during the rearrangement of isoxazol-5-yl hydrazine 1 to 1-aminopyrazolone 2 at 115°. X-ray analysis of the corresponding benzylidene derivative allowed us to achieve the structure assignment.
