Reaction Conditions:

with hydrazine hydrate at 40 - 75; for 4 h;Green chemistry;Large scale;Temperature;

Steps:

1.1 Example 1 Preparation of pymetrozine.
(1) Preparation of hydrazide:1000 g of methyl acetate (solvent) was put into a 3000 ml three-necked flask,Under stirring conditions,500 g of hydrazine hydrate was slowly added dropwise to the three-necked flask, and the dropping time was controlled to 2 hours. The temperature of the reaction solution was controlled to 40 to 45C.After the dropwise addition, the temperature was raised to 75 ° C for 4 h. Cooled to room temperature,After solidification and crystallization (cooling to below 0 ° C) to give solid acetylHydrazine 725 g, yield: 98%.
