with sodium acetate in water at 95 - 100; for 3 h;Reagent/catalyst;Solvent;Temperature;
Steps:
2-6 Example 4 Synthesis of metribuzin
140 g of methylthiocarbazone and 18 g of anhydrous sodium acetate in Example 1 were added to a four-necked bottle.Add 150g of water,Heating up to 95 ° C,130 g of 3,3-dimethylbutyric acid dione was added in three batches.After the addition, the temperature was kept at 95-100 ° C for 3 h.Sampling analysis ends the reaction.Cool down to 30-35 ° C,After filtration, it is dried to obtain a purity of 97% or more of oxazinone 204g.The yield was 95.3%
