1-aryl-1H-pyrazol-5-aminer fremstilles af aryl hydraziner kombineret med enten 3-aminocrotononitril eller en α-cyanoketon i en 1 M HCL-opløsning ved hjælp af en mikrobølge reaktor. De fleste reaktioner er udført i 10-15 minutter og rent produkt kan opnås via vakuum filtrering med typiske isolerede udbytter på 70-90%.
