Methyl 2-(4-methoxybenzylamino)acetate (760 mg, 3.63 mmol) and triethylamine (840 μL, 6.60 mmol) were successively added to a solution of 5-bromo-3-(bromomethyl)pyridine-2-amine hydrobromide (1.0 g, 3.30 mmol) in DMF (17 mL) at room temperature. The reaction mixture was stirred for 8 hours then diluted by addition of water (50 mL) and ethyl acetate (50 mL). The aqueous phase was separated and extracted with ethyl acetate (3×50 mL). The combined organic phases were washed with a saturated solution of sodium chloride (3×50 mL), dried over sodium sulphate, filtered and concentrated to dryness. The title compound was obtained as an orange oil (1.05 g, 93%) which was used in the next step without further purification.
