YieldReaction ConditionsOperation in experiment
With hydrazine hydrate; In ethanol; at 20 - 75℃; 100 g (645 mmol) of methyl (2E/Z)-2-cyano-3-ethoxyacrylate were initially charged in 481 ml of ethanol. 31 ml (645 mmol) of an 85% strength hydrazine hydrate solution were then added dropwise at room temperature with cooling (exothermal temperature.) over a period of 45 minutes. The mixture was stirred at 75 C. for another 12 hours. The hot mixture was filtered and the organic phase was concentrated under reduced pressure. This gave 64 g of methyl 5-amino-1H-pyrazole-4-carboxylate (log P =-0.07; HPLC content: 86%).
