Procedure

To a stirred solution of (3-methoxy-4-((6-methoxypyridin-3-yl)methoxy)phenyl)methanamine (5.00 g, 18.23 mmol) in acetonitrile (75 mL) was added 1-fluoro-4-iodo-2-nitrobenzene (4.55 g, 17.04 mmol) and diisopropylethylamine (3.30 g, 25.56 mmol). The yellow solution was heated to reflux and stirred. After 4 h, the orange-brown mixture was allowed to cool to room temperature and was diluted with water (150 mL). The resulting bright orange precipitate was isolated by filtration and washed with water. 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 7.10 g (80%) of 4-iodo-N-(3-methoxy-4-((6-methoxypyridin-3-yl)methoxy)benzyl)-2-nitroaniline as a bright orange solid.
