氟啶胺的制备方法

Preparation of Fluazinam

采用2,3-二氯-5-三氟甲基吡啶为原料,经氨解反应得到2-氨基-3-氯-5-三氟甲基吡啶,再与2,4-二氯-3,5-二硝基三氟甲苯经缩合反应得到高效农药杀菌剂氟啶胺。

2,3-dichloro-5-trifluoromethyl pyridine as raw material,obtains 2-amino-3-chloro-5-trifluoromethylpyridine through ammonolysis reaction,and then condenses with 2,4-dichloro-3,5-dinitrotrifluoromethyl toluene to obtain highly effective pesticide fungicide Fluazinam.
