Reaktionsschritte

A suspension of 5-bromo-pyridine-2,3-dicarboxylic acid (700 mg, 2.85 mmol) in acetic anhydride (0.88 ml, 9.39 mmol, 3.3 equiv.) was heated at 80° C. for 10 min and then refluxed for 1 h. Acetic anhydride was evaporated off in vacuo. The resulting solid was triturated with hexane to afford 3-bromo-furo[3,4-b]pyridine-5,7-dione (510 mg, 79%) as off white solid.
