Chloroactone (82 mL) was added dropwise to a suspension of N-(6-bromo-2-methoxypyridin-3-yl)formamide (159.3 g), cesium carbonate (359 g) and potassium iodide (11.4 g) IN DMF (800 mL) over seven minutes. Then, the reaction solution was stirred at room temperature for one hour and 20 minutes. The reaction solution was concentrated under reduced pressure. Ethyl acetate and water were added to the resulting residue, and the organic layer was separated. The resulting organic layer was washed with brine, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure to obtain 215.2 g of the title compound. The property values of the compound are as follows.
