The Synthesis of Some Derivatives Based on the 4-Benzyl-1H-pyrazole-3,5-diamine Core
The three-step synthesis of 4-benzyl-1H-pyrazole-3,5-diamines 2 from to benzylmalononitriles 5. Subsequent cycloaddition of hydrazine with 5 afforded the desired pyrazoles 2. Due to the high similarity with 4-arylazo-1H-pyrazole...
