Procedure

A mixture of 5-[4-(methoxymethoxy)phenyl]-1-(4-methoxyphenyl)-1H-pyrazol-3-amine obtained by Example 20-2 (3.79 g), lithium chloride (2.47 g), and copper (II) chloride (3.13 g) in acetonitrile (60 ml) was stirred at room temperature for 10 min. To this mixture was added isoamyl nitrite (2.73 g), and the mixture was stirred at room temperature for 1 hr.
