実験手順
In the same apparatus and following the same modalities as in Example 1, 5 g (0.0255 mole) of 1-(m-chlorophenyl)-3-amino-2-pyrazoline were suspended in 25 ml of ethanol with addition of 0.2 g of CuCl, under an oxygen head. Oxidation was concluded after about 3 hours. The oxidized product was recovered as in Example 1, obtaining 3.6 g of 1-(m-chlorophenyl)-3-aminopyrazole, melting at 106°-107° C.
後処理
- customThe oxidized product was recovered as in Example 1
