Procedure

To a stirred solution of (3-methoxy-4-((6-methoxypyridin-3-yl)methoxy)phenyl)methanamine (9.11 g, 33.21 mmol) in acetonitrile (150 mL) was added 2-chloro-5-iodo-3-nitropyridine (9.90 g, 34.81 mmol) and N,N-diisopropylethylamine (6.44 g, 49.81 mmol). The yellow solution was heated to reflux and stirred. After 3 h, the red-brown mixture was cooled to 0° C. resulting in the formation of a precipitate. The precipitate was isolated by filtration and washed with acetonitrile (50 mL) and water (200 mL). The moist solids were dissolved in dichloromethane, and a small amount of water separated and was removed. The organic phase was dried over magnesium sulfate, filtered, and concentrated to provide 14.67 g (85%) of 5-iodo-N-(3-methoxy-4-((6-methoxypyridin-3-yl)methoxy)benzyl)-3-nitropyridin-2-amine as a yellow-brown solid.
