Versuchsvorschrift

A mixture of N2-(2,2,2-trifluoroethyl)-5-trifluoromethylpyridin-2,3-diamine (0.52 g), 3-ethylsulfanylpyridin-2-carboxylic acid (0.37 g), WSC (0.46 g), HOBt (27 mg) and pyridine (2 ml) was stirred at room temperature for 3 hours. To the reaction mixture was poured aqueous 10% citric acid solution, and then the mixture was extracted with ethyl acetate. The organic layer was washed with water, dried over sodium sulfate, and concentrated under reduced pressure to give 3-ethylsulfanyl pyridin-2-carboxylic acid [2-(2,2,2-trifluoroethyl)amino-5-trifluoromethylpyridin-3-yl]amide (0.75 g), which is hereinafter referred to as “intermediate compound (M3-43)”.
