| titleOfInvention | A kind of preparation method of kresastrobin |
| abstract | The invention provides a preparation method of kysastrobin. The method utilizes 2-halomethylhalobenzene and 2,5-dimethylphenol to prepare 2-(2,5-dimethylphenoxymethyl)halogenated benzene through etherification reaction, and then reacts with metal magnesium The Grignard reaction prepares the corresponding Grignard reagent, and the resulting reaction solution containing the Grignard reagent is added dropwise to N-methyl oxalic acid monoester monoamide to prepare N-methyl-2-(2,5-dimethylphenoxymethanol Base) phenyl oxamide, and finally prepare kresastrobin through condensation reaction with methoxyamine salt. The method of the present invention has cheap and easy-to-obtain raw materials and low cost; the process flow is short, and only three steps of reaction can be used to prepare kresastrobin; the reaction conditions are easy to realize, the operation is safe and convenient, the process wastewater is produced in a small amount, and the environment is green; the raw materials and intermediate products The method has high stability, high reactivity and selectivity, and few side reactions; the obtained kysoxazim has few impurities, high purity and high yield, and is beneficial to the industrial production of kysoxazim. |
