Методика

In the same apparatus and following the same modalities as in Example 1, 1 g (0.00416 mole) of 1-(p-bromophenyl)-3-amino-2-pyrazoline was suspended in 10 ml of ethanol with addition of 0.04 g (0.0004 mole) of CuCl and of 0.013 g (0.0002 mole) of Cu, under an oxygen head. Oxidation was concluded after about 3 hours. The oxidized product was recovered as in Example 1, thus obtaining 0.5 g of 1-(p-bromophenyl)-3-aminopyrazole, of melting point 122°-123° C.
