To a stirred solution of (3-methoxy-4-((6-methylpyridin-3-yl)methoxy)phenyl)methanamine (7.30 g, 28.26 mmol) in acetonitrile (200 mL) was added 2-chloro-5-iodo-3-nitropyridine (8.44 g, 29.67 mmol) and N,N-diisopropylethylamine (5.48 g, 42.39 mmol). The brown mixture was heated to reflux. After 5 h, the brown mixture was allowed to cool to room temperature and was diluted with water (600 mL). The resulting precipitate was isolated by filtration and washed with water (200 mL). The moist solids were dissolved in ethyl acetate (300 mL), and this solution was washed with water (100 mL). The organic phase was dried over magnesium sulfate, filtered, and concentrated to provide 13.57 g (95%) of 5-iodo-N-(3-methoxy-4-((6-methylpyridin-3-yl)methoxy)benzyl)-3-nitropyridin-2-amine as a bright yellow solid.
