经两步反应合成了 3 氨基 4 腈基吡唑 :丙二腈与原甲酸三乙酯反应得到乙氧亚甲基丙二腈 ;其产物再与水合肼反应得到 3 氨基 4 腈基吡唑 ,总收率为 6 8.3%
3-amino-4-nitrile-pyrazole was synthesized via two steps: the reaction of malononitrile with triethyl orthoformate gave ethoxymethylenemalononitrile; the product was then reacted with hydrazine hydrate to give the 3-amino-4-nitrilepyrazole, The total yield is 6 8.3%
