What is the preparation method of α, α, α-trifluoro p-toluidine

To make α,α,α - trifluoro-p-toluyl, the method is as follows:

Take p-methylbenzoic acid first, place it in a clean kettle, and mix it with an appropriate amount of halogenating agent. This halogenating agent should be selected to introduce fluorine atoms into its structure, such as a specific fluorine-containing halogenating agent, and should be accurately measured according to its reaction ratio. Then, the temperature is controlled in a moderate range. This temperature needs to be confirmed by many tests. If the temperature is too high or side reactions are caused, the reaction will be delayed if it is too low. Stir slowly to make the two fully blend and promote the reaction. < Br >
After the halogenation reaction is completed, the mixture obtained by the reaction is moved to a separator, and the impurities are removed by methods such as distillation and extraction to obtain a product containing α-halogenated p-methylbenzoic acid.

Repeat this product, add it to another reactor, and add an appropriate amount of fluorinating agent. This fluorinating agent also needs to be carefully selected, and its activity and selectivity are related to the success or failure of the reaction. Still controlled temperature and stirred to make the fluorination reaction occur smoothly, so that the halogen atom is gradually replaced by a fluorine atom, and finally α,α,α - trifluoro-p-methylbenzoic acid.

Then, with appropriate reagents, the α,α,α - trifluoride p-toluic acid is acylated.
