• Synthesis

  2-Amino-5-bromo-3-(hydroxymethyl)pyridineBromine (8.4 mL, 189.4 mmol) was added dropwise over 1 hour to a solution of 2- amino-3-(hydroxymethyl)pyridine (19.6 g, 157.8 mmol) in acetic acid (350 mL) at room temperature. The reaction mixture was then stirred overnight. After concentration to dryness, the residue was partitioned between a saturated solution of potassium carbonate (300 mL) and ethyl acetate (200 ml_). The aqueous layer was separated and extracted with ethyl acetate (2 x 200 ml_). The combined organic phases were washed with a saturated solution of sodium chloride (200 ml_), dried over sodium sulfate, filtered and concentrated to dryness. After trituration of the residue in pentane, the title product was obtained as a yellow solid (27.0 g, 84%).
