1-aryl-1H-pyrazole-5-aminer fremstilles fra aryl hydrazines kombinert med enten 3-aminocrotononitrile eller en α-cyanoketone i en 1 M HCL-løsning ved hjelp av en mikrobølgeovn reaktor. De fleste reaksjonene er gjort i 10-15 minutter og rent produkt kan fås via vakuum filtrering med typiske isolerte avlinger på 70-90%.
