Reaktionsschritte

A mixture of 0.81 g of 2-amino-6-trifluoromethylpyridine, 0.78 g of 3-chloropicolinic acid, 1.15 g of EDCI hydrochloride, 0.06 g of HOBt and 10 mL of pyridine was stirred at 70° C. for 2 hours. A saturated aqueous sodium bicarbonate solution was poured to the cooled reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and then concentrated under reduced pressure, and the resulting solid was washed with hexane and dried to obtain 1.33 g of 3-chloro-N-(6-trifluoromethylpyridin-2-yl)picolinamide.
