What are the synthesis methods of 3,5-dichloro-2-fluoro-4- (1,1,2,3,3,3-hexafluoropropoxy) aniline

To prepare 3% 2C5-difluoro-2-chloro-4- (1,1,2,3,3,3-hexafluoropropoxy) anisole, the method is as follows:

First take an appropriate amount of 2,5-difluorophenol, place it in the reaction kettle, add an appropriate amount of alkaline substances, such as potassium carbonate, stir well, so that the system is in an alkaline environment. Then, slowly add 1,1,2,3,3,3-hexafluoropropyl chloride, control the reaction temperature and dripping speed to ensure the smooth progress of the reaction. The purpose of this step is to introduce 1,1,2,3,3,3-hexafluoropropoxy at the hydroxyl position of 2,5-difluorophenol through nucleophilic substitution reaction. The reaction process needs to be closely monitored during the reaction process, and thin-layer chromatography can be used.

After the first step of the reaction is completed, the reaction system is cooled, and a suitable halogenating agent, such as thionyl chloride, is added. Halogenation reaction is carried out at a specific position on the benzene ring, so that the benzene ring is introduced into the chlorine atom at a specific position. During the reaction, pay attention to the control of the amount of halogenating agent and the reaction conditions to avoid side reactions such as excessive halogenation.

After the halogenation reaction is completed, the product is preliminarily separated, and impurities are removed by After that, an appropriate amount of methylation reagent, such as dimethyl sulfate, is added to the reaction system, and the methylation reaction is carried out under basic conditions, so that the methoxy group is introduced at another suitable position of the benzene ring to obtain the target product 3% 2C5 -difluoro-2-chloro-4 - (1,1,2,3,3-hexafluoropropoxy) anisole. Finally, the product is further purified, and column chromatography and other methods can be used to improve the purity of the product.

Each step of the reaction requires fine control of the reaction conditions, including temperature, time, and the proportion of reactants, etc., and accurate analysis and identification of the intermediate and final products are required to successfully prepare the target product.

What are the physicochemical properties of 3,5-dichloro-2-fluoro-4- (1,1,2,3,3,3-hexafluoropropoxy) aniline
