Reaction Steps

5-Bromo-pyridin-2-carbaldehyde (2.0 g, 10.6 mmol), malonic acid (2.5 g, 24.2 mmol), and piperidine (0.9 mL, 9.0 mmol) were added to pyridine (6.5 mL). The reaction mixture was stirred at 100° C. for 1 hour and then concentrated under reduced pressure. Distilled water was added to the reaction mixture, which was then filtered. The resulting solid was dried under reduced pressure to give 1.3 g of the titled compound as a brown solid.
