実験手順

A mixture of 2.0 g. of 3-amino-1-(m-chlorophenyl)-2-pyrazoline (prepared in Example 10) and 10 ml. of a mixture of formic acid and acetic anhydride (Example 15) is allowed to stand at room temperature for 30 minutes. Then the solvent is evaporated in vacuo to give an oil. The oil is dissolved in dichloromethane and is columnized and recrystallized as described in Example 5 to give 1.32 g. of the desired product as pale yellow needles, m.p. 143°-145° C.
