Adding a certain compound to certain chemical reactions, such as: 16075-42-6, 2-Amino-4-(trifluoromethyl)pyrimidine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, name: 2-Amino-4-(trifluoromethyl)pyrimidine, blongs to pyrimidines compound. name: 2-Amino-4-(trifluoromethyl)pyrimidine
General procedure: Two mmol 5b1-5b20 was added to a dichloromethane solution containing 0.3 mL triethylamine at 0 C. Then 1.2 equiv. 3-chloropropionyl chloride was dissolved in dry dichloromethane, and the obtained mixture was slowly added to the aniline solution at 0 C. The reaction mixture was allowed to slowly warm up to room temperature, extracted with dichloromethane and finally washed with 2 M HCl. The organic phase was combined and dried with anhydrous MgSO4. Filtration and removal of the solvent under reduced pressure gave the crude product. The desired product was further purified by flash column chromatography with petroleum ether-EtOAc (20:1 to 10:1) to produce 6b1-6b20.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,16075-42-6, 2-Amino-4-(trifluoromethyl)pyrimidine, and friends who are interested can also refer to it.
