Synthesis
74784-70-6
79456-30-7
The general procedure for the synthesis of 2-amino-3-bromo-5-trifluoromethylpyridine from 2-amino-5-trifluoromethylpyridine was as follows: 71 g of N-bromosuccinimide was added in batches to a mixture containing 65 g of 2-amino-5-trifluoromethylpyridine and 100 ml of chloroform under cooling conditions in an ice-water bath, with the temperature increasing during the reaction. Subsequently, the reaction mixture was stirred at room temperature for 1 hour. Next, the reaction mixture was heated to 80°C and stirred at this temperature for 30 minutes. Upon completion of the reaction, the mixture was cooled to room temperature and quenched by sequentially adding saturated aqueous sodium thiosulfate and saturated aqueous sodium bicarbonate, followed by extraction with chloroform. The organic layers were combined, dried with anhydrous sodium sulfate and concentrated under reduced pressure to remove the solvent. Finally, the residue was purified by silica gel column chromatography to give 96 g of the target product 2-amino-3-bromo-5-trifluoromethylpyridine. The structure of the product was confirmed by 1H-NMR (CDCl3): δ 8.27 (1H, d), 7.86 (1H, d), 5.38 (2H, brs).
