Reaction Conditions:
with hydrazine hydrate in methanol at 70;
Steps:
1
33.9 g (163 mmol) of methyl 4-butoxybenzoate, 150 ml of hydrazine hydrate (80%) and 500 ml of methanol were added to a 1000 ml three-necked flask, and heated to reflux at 70 °C. After the reaction was completed, the reaction solution was spin-dried to obtain a white solid. The white solid was washed three times with water and filtered to finally obtain 30 g of 4-butoxybenzoylhydrazide (yield: 91%)
