What is the production method of 3,5-difluorobenzyl amine?

The method of preparing 3,2,5-diacetamidopyridine is as follows:

First take an appropriate amount of pyridine and place it in a clean reactor. The temperature is slowly reduced to a suitable low temperature in an ice-water bath, usually about 0 to 5 degrees Celsius. In this low temperature environment, an appropriate amount of acetic anhydride is added dropwise. The rate of dropwise addition needs to be carefully controlled to prevent the reaction from being too violent. During the dropwise addition of acetic anhydride, continue to stir so that the reactants are fully mixed.

After the dropwise addition of acetic anhydride is completed, remove the ice-water bath and let the reaction system continue to react at room temperature for a period of time. During this period, the reaction process can be closely observed, and the degree of reaction can be monitored by means of < Br >
After the reaction reaches the desired level, slowly add an appropriate amount of water to the reaction system to quench the unreacted acetic anhydride. After that, the reaction mixture is transferred to a separation funnel and extracted with a suitable organic solvent, such as dichloromethane. After multiple extractions, the organic phases are combined.

The organic phase is dried with an appropriate amount of anhydrous sodium sulfate to remove the moisture contained in it. Subsequently, the organic solvent is evaporated under suitable temperature and pressure conditions using a rotary evaporator to obtain a crude product.

The crude product is further purified by column chromatography. Select a suitable silica gel as the stationary phase, and elute with a suitable proportion of eluent, such as a mixture of petroleum ether and ethyl acetate. Collect the eluent containing the target product, steam the solvent again, and finally obtain a pure 3,2,5-diacetamidopyridine product.

This preparation method requires attention to the precise control of the reaction temperature, the speed of dropwise reagent addition, and the connection between each step to ensure the yield and purity of the product.

What are the precautions for using 3,5-difluorobenzyl amine?

3,2,5-Diethylbenzoic acid is also an organic compound. When using it, the number of ends should be paid attention to.

First safety protection. This substance has a certain chemical activity, and contact with it may cause skin and eye irritation. Therefore, when using it, wear suitable protective equipment, such as gloves and goggles. If you accidentally touch the skin, rinse quickly with a lot of water. If it enters the eyes, rinse immediately and seek medical attention.
