Method for simply synthesizing pyraclostrobin

The invention discloses a method for simply synthesizing pyraclostrobin. The method comprises steps as follows: N-hydroxyl-N-2-[1-(4-chlorophenyl)-3-pyrazoloxy methyl]phenyl carbamate and a phase transfer catalyst are dissolved in an organic solvent, dimethyl sulfate is added, an acid-binding agent is dropwise added at the system temperature kept in a range of 5-70 DEG C, the components react for 1-5 h, and pyraclostrobin is obtained. Under the condition of reasonable control of feeding sequence of reaction raw materials and the system temperature, the problems of many reaction by-products as well as potential safety hazard and the like due to the many reaction by-products in an existing pyraclostrobin synthesis process are effectively solved, and a plurality of advantages such as reduction of production cost, reduction of wastewater quantity in a production process and the like can be provided for industrial production, so that the method is beneficial to energy conservation, emission reduction and environment protection of pesticide chemical enterprises and is more suitable for large-scale industrial production.
