Procedure
In a manner similar to that described in Example 53, 4-(quinolin-5-ylhydrazono)-4H-pyrazole-3,5-diamine was prepared. 5-Aminoquinoline (0.35 g), malononitrile (0.3 g) and hydrazine hydrate (0.3 mL) yielded 0.043 g of the title compound after the purification by preparative TLC (⅓ of the crude product).
