5‐Isoxazolylhydrazines rearranged to 1‐aminopyrazolin‐5‐ones on heating. Under the same conditions, 5‐(3‐methyl‐4‐phenylisoxazolyl)hydrazine also gave 3‐methyl‐4‐amino‐4‐phenylpyra‐zolin‐5‐one. The structures of aminopyrazolones were assigned on the basis of spectroscopic properties and chemical behavior.
