実験手順

Example 1 was repeated using the following amounts of reagents: 5 g (0.031 mole) of 1-phenyl-3-amino-2-pyrazoline were dissolved in 25 ml of acetonitrile under addition of 0.2 g (0.00201 mole) of CuCl, under an oxygen head. Oxidation lasted about 3 hours. 2.5 g of 1-phenyl-3-aminopyrazole were obtained.
