Reaction Steps
Bromine (1.1 mL, 20 mmol) in HOAc (20 mL) was added dropwise to a solution of 2-amino-pyridine-3-carbaldehyde (2.5 g, 20 mmol) in HOAc (50 mL) while stirring. After the addition, the mixture was allowed to stir for 2 h at room temperature. The precipitate was collected by filtration and washed with diethyl ether to afford the title compound (4.4 g, 77%) as a pale yellow solid: MS (ESI) m/e 201 (M+H)+.
