Reaction Steps

Under the atmosphere of nitrogen gas, 15.0 g (109 mmol) of 2-nitroaniline, 17.2 g (109 mmol) of 2-bromopyridine, 2.06 g (10.9 mmol) of copper iodide and 30 g (218 mmol) of potassium carbonate were stirred with heating at the temperature of 160° C. for 9 hours. The reacted solution was cooled down to room temperature, diluted with ethyl acetate and filtered. After concentrating the filtrate, it was refined with silicagel column chromatography, and 6.30 g of 2-nitro-N-pyridyl aniline was obtained (yield: 27%).
