Procedure

To a stirred solution of (3-ethoxy-4-((6-methoxypyridin-3-yl)methoxy)phenyl)methanamine (2.75 g, 9.54 mmol) in acetonitrile (50 mL) was added 2-chloro-5-iodo-3-nitropyridine (2.85 g, 10.01 mmol) and N,N-diisopropylethylamine (1.85 g, 14.31 mmol). The resulting yellow mixture was heated to reflux. After 3 h, the red-brown solution was allowed to cool to room temperature, resulting in the formation of a precipitate. The solids were isolated by filtration and washed with water (200 mL). The moist solids were dissolved in dichloromethane (100 mL), and a small amount of water separated and was removed. The solution was dried over magnesium sulfate, filtered, and concentrated to provide 4.34 g (85%) of N-(3-ethoxy-4-((6-methoxypyridin-3-yl)methoxy)benzyl)-5-iodo-3-nitropyridin-2-amine as an orange solid.
