Synthetic technology for pyraclostrobin

ActiveCN104211641AFormation reaction is easy to controlSmooth responseOrganic chemistryMethylanilineChlorobenzene
The invention concretely relates to a synthetic technology for pyraclostrobin. The synthetic technology comprises: firstly performing cyclization to obtain 1-(4-chlorophenyl)-pyrazol-3-one, oxidizing the pyrazol ring under the effect of an oxidant to generate 1-(4-chlorophenyl)-3-hydroxypyrazole, then using 2-nitrobenzyl bromide to performing etherification to generate 1-(4-chlorophenyl)-3-[2-(nitrophenyl)methoxy]-1H-pyrazole, then using a reducing agent to perform nitro reducing, so as to generate N-hydroxyl-2-[N'-(4-chlorophenyl)pyrazol-3'-yloxymethyl]aniline, then using ClCO2CH3 to perform N-acylation reaction to generate methyl N-hydroxyl-N-2-{[N'-(4-chlorophenyl)pyrazol-3'-yloxymethyl]phenyl}formate, and finally performing hydroxyl methylation under an alkaline condition to generate pyraclostrobin. The technology enables all operations in the pyraclostrobin preparation process to be relatively controllable, helps to improve the stability of the preparation process and improve the product yield, successfully employs low-cost reagents and substantially reduces production cost, and also the employed reagents are relatively small in toxicity, is relatively beneficial for environment protection, and has no corrosivity on plastic pipes, so that the production safety is improved.
