| titleOfInvention | Method for synthesizing 2-mercapto-3-difluoromethyl benzoxazole compound |
| abstract | The invention discloses a method for synthesizing a 2-mercapto-3-difluoromethyl benzoxazole compound, which comprises the following steps: taking sodium chlorodifluoroacetate and sulfur powder as reactants, taking an o-aminophenol derivative as a substrate, heating to 50-120 ℃ in a solvent under an alkaline condition, stirring for 2-12h, and after the reaction is finished, treating a reaction solution to obtain the 2-mercapto-3-difluoromethylbenzoxazole compound. The synthesis method has the advantages of generally high yield, easily obtained raw materials, simple and convenient operation, wide substrate and the like, and has good industrial application prospect. |
