Synthesis method of oxetsulam

The invention discloses a synthetic method of metamifop. The reaction of R - 2 - ((4 -chlorobenzo [R - 2 -] oxazol 4 -yloxy) phenoxy) propionic acid potassium salt, 2-(6 -chlorobenzo [R - 2 -] oxazol 4 -yloxy) phenoxy) propionic acid potassium salt by rea

Synthetic method of metamifop

The invention relates to the field of organic synthesis, in particular to a synthesis method of high-purity metamifop, the synthesis method comprises the following step: carrying out substitution reaction on fenoxaprop-p-ethyl and N-methyl o-fluoroaniline under the action of a catalyst to obtain the high-purity metamifop. The synthesis method of the metamifop provided by the invention is simple inreaction operation, a reaction system is nearly neutral, conditions are mild, and metamifop cannot be decomposed; the fenoxaprop-p-ethyl serving as the raw material is mature in production and high in purity, impurities cannot be brought into the fenoxaprop-p-ethyl by the raw material, and the prepared metamifop is high in purity and good in quality. The method is simple in process, free of threewastes, environmentally friendly, free of dangerous steps, safe, reliable and capable of achieving large-scale industrial production.
