Reaction Steps

To a solution of 2-(3-aminomethylphenyl)-4-nitroanisole hydrochloride (1.26 g, 4.2 mmol) in methanol (10 mL) and tetrahydrofuran (10 mL) under nitrogen was added palladium on carbon (10% by weight, 200 mgs, 15 wt. %). The solution was purged with hydrogen and stirred under hydrogen for 24 hours. The reaction was purged with nitrogen and the catalyst was removed by filtration. Solvent was removed in vacuo and the residue was redissolved in dichloromethane (10 mL) and hydrochloride acid was added (4.0 M solution in dioxane, 1.5 equiv., 1.57 mL). The solution was stirred for 1 hour while a solid precipitated. The solid was collected on a Buchner funnel and dried under vacuum to afford 3-(3-aminomethylphenyl)-4-methoxyaniline dihydrochloride (947 mgs, 73% yield).
