| titleOfInvention | A kind of preparation method of phenoxyacetic acid derivatives |
| abstract | The invention discloses a preparation method of phenoxyacetic acid derivatives. The method adopts a one-step synthesis method. Under alkali catalysis, (E)-2,6-dimethyl-4-(3-(4-( Methylthio) phenyl)-3-oxoprop-1-ene-1-yl) phenol reacts with 2-bromoisobutyric acid to obtain. The preparation method simplifies the process route, the product is easy to separate and purify, and the operation is simple and efficient; at the same time, a large number of strong acids and brominated reagents are avoided, which is economical and environmentally friendly; in addition, the reaction efficiency is high, the reaction time is shortened, the material utilization rate is high, and the total product yield is 75% or more, and the product purity reaches more than 99%. |
