Reaction Steps

Pd/C (10%, 11.49 g) was added to a three-neck flask. A gentle nitrogen flow was applied to the flask. Water (40 mL) and methanol (800 mL) were added to the flask. Then, N2-phenylpyridine-2,3-diamine (20 g, 108 mmol), formaldehyde (8.76 g, 108 mmol), and ammonium formate (136 g, 2160 mmol) were added. The reaction was stirred at room temperature overnight. The solution was filtered through a Celite® plug. The filtrate was concentrated and water was added. The solution was extracted with dichloromethane. The combined organic layer was concentrated and purified by column chromatography (30% ethyl acetate in hexanes) to give N3-methyl-N2-phenylpyridine-2,3-diamine (12 g, 55.8% yield).
