Reaction Steps

To a stirred suspension of 4-iodo-N-(1-(3-methoxy-4-((6-methoxypyridin-3-yl)methoxy)phenyl)ethyl)-2-nitroaniline (3.17 g, 5.92 mmol) and ammonium chloride (2.53 g, 47.37 mmol) in tetrahydrofuran (50 mL)/methanol (20 mL)/water (10 mL) was added iron(II) sulfate heptahydrate (5.76 g, 20.73 mmol) and zinc dust (1.35 g, 20.73 mmol). The resulting mixture was heated to reflux. After 1 h, the mixture was allowed to cool to room temperature and was filtered through Celite. The filtercake was washed with methanol (50 mL). The filtrate was concentrated, and the residue was diluted with 3N ammonium hydroxide solution (100 mL). The basic mixture was extracted with chloroform (3×50 mL), and the combined organic phases were dried over magnesium sulfate, filtered, and concentrated to provide 2.02 g (68%) of 4-iodo-N1-(1-(3-methoxy-4-((6-methoxypyridin-3-yl)methoxy)phenyl)ethyl)benzene-1,2-diamine as a brown solid.
