Reaction Steps

4-Bromo-pyridin-2-carbaldehyde (10.0 g, 53.5 mmol), malonic acid (12.5 g, 120.5 mmol), and piperidine (4.4 mL, 44.4 mmol) were added to pyridine (32.5 mL). The reaction mixture was stirred at 100° C. for 1 hour, concentrated under reduced pressure, and then distilled water was added thereto. The mixture was filtered and then the resulting solid was dried under reduced pressure to give 6.3 g of the titled compound as a white solid.
