Versuchsvorschrift

Example 1 was repeated using the following amounts of reagents: 5 g (0.031 mole) of 1-phenyl-3-amino-2-pyrazoline were suspended in 25 ml of ethanol and 2 ml of H2O, under addition of 0.1 g (0.001 mole) of CuCl and 0.064 g (0.001 mole) of Cu, under an oxygen head. Oxidation lasted about 3 hours. 3.9 g of 1-phenyl-3-aminopyrazole were obtained.
