Reaction Steps

To a stirred suspension of 4-bromo-N-(3-methoxy-4-((4-methoxybenzyl)oxy)benzyl)-2-nitroaniline (7.71 g, 16.30 mmol) in tetrahydrofuran (100 mL), ethanol (25 mL), and water (25 mL) was added ammonium chloride (0.44 g, 8.15 mmol) and iron powder (9.10 g, 163 mmol). The mixture was heated to reflux. After 5 h, the reaction mixture was allowed to cool to room temperature and was filtered through Celite with the aid of ethanol. The filtrate was concentrated, and the residue partitioned between dichloromethane and water. The organic phase was separated, dried over magnesium sulfate, filtered, and concentrated to provide 6.73 g (95%) of 4-bromo-N1-(3-methoxy-4-((4-methoxybenzyl)oxy)benzyl)benzene-1,2-diamine as a brown solid.
