Reaction Steps

A mixture of 0.81 g of 2-amino-5-trifluoromethylpyridine, 1.13 g of 3-chloro-5-trifluoromethylpicolinic acid, 1.15 g of EDCI hydrochloride, 0.06 g of HOBt and 10 mL of pyridine was stirred at 60° 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 residue was applied to a silica gel column chromatography to obtain 1.35 g of 3-chloro-5-trifluoromethyl-N-(5-trifluoromethylpyridin-2-yl)picolinamide.
