Reaction Steps

5 g (25.1 mmol) of 6-phenoxy-pyridine-3-carbaldehyde were dissolved in 50 ml of pyridine, and 3.134 g (30.1 mmol) of malonic acid and 213 mg (2.5 mmol) of piperidine were added. The reaction mixture was boiled under reflux for 6 h. After cooling to room temperature, it was poured into a mixture of ice and concentrated hydrochloric acid. The precipitated product was isolated by filtration. Yield: 5.66 g.
