Related Products of 80194-68-9, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 80194-68-9, name is 3-Chloro-5-(trifluoromethyl)picolinic acid. A new synthetic method of this compound is introduced below.
A mixture of 2-amino-4-(trifluoromethylsulfanyl)phenol 1.0 g, 3-chloro-5-trifluoromethylpicolinic acid 1.08 g, EDC hydrochloride 1.10 g, and chloroform 10 mL was stirred at RT for 1 hr. To the reaction mixture was added water, and the resulting mixture was extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium bicarbonate, water, and brine, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure to give 3-chloro-5-trifluoromethyl-N-[2-hydroxy-5-(trifluoromethylsulfanyl)phenyl]picolinamide 1.94 g. 3-chloro-5-trifluoromethyl-N-[2-hydroxy-5-(trifluoromethylsulfanyl)phenyl]picolinamide 1H-NMR(CDCl3)delta: 8.78(1H, d), 8.15(1H, d), 8.09(1H, d), 7.37(1H, dd), 7.04(1H, d).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,80194-68-9, 3-Chloro-5-(trifluoromethyl)picolinic acid, and friends who are interested can also refer to it.
