1-aril-1H-pyrazole-5-aminas são preparados a partir de aril hidrazinas combinada com 3-aminocrotononitrila ou um α-cyanoketone em uma solução de HCl de 1 M usando um reator de microondas. A maioria de reações são feitas em 10-15 minutos e o produto puro pode ser obtido através da filtração do vácuo com rendimentos isolados típicos de 70-90%.
