Versuchsvorschrift
A solution of bromine (1.05 mL, 20.0 mmol) in acetic acid (20 mL) was added to a solution of 2-amino-3-pyridinecarboxaldehyde (2.5 g, 20 mmol) in acetic acid (50 mL) at room temperature. The reaction mixture was then stirred overnight. The resulting precipitate was filtered and washed with diethyl ether to give the title compound as a white solid (4.66 g, 80%).
