To a pressure-resistant reaction container, (2-chloro-6-trifluoromethylpyridin-3-yl)-methylamine (2.60 g), copper (II) acetylacetone (0.64 g), acetylacetone (1.23 g), cesium carbonate (7.99 g), NMP (10 ml), and 28% of aqueous ammonia (7 ml) were added, and stirred at 140° C. for 8 hours. After the mixture was allowed to cool to room temperature, saturated aqueous ammonium chloride solution was poured thereinto, and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, and concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography to give 2.09 g of N3-methyl-6-trifluoromethylpyridin-2,3-diamine.
