Reaction Conditions

Reaction Steps

A mixture of 1.62 g of 2-amino-5-trifluoromethylpyridine, 2.5 g of 2-ethylsulfanyl-4-trifluoromethylbenzoic acid, 2.3 g of EDCI hydrochloride, 0.13 g of HOBt and 5 mL of pyridine was stirred at room temperature for 2 hours and at 60° C. for 1 hour. A saturated aqueous sodium bicarbonate solution was added 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 2.56 g of 2-ethylsulfanyl-4-trifluoromethyl-N-(5-trifluoromethyl-pyridin-2-yl)-benzamide.
