Reaction Steps

2-Oxo-5-phenyl-1,2-dihydropyridine-3-carbonitrile (2.50 g, 12.7 mmol) was added to a suspension of POCl3 (1.5 ml) and PCl5 (7.35 g) at room temperature. The suspension was then stirred at reflux for 1 hour. The reaction mixture was cooled to room temperature and added cautiously to iced water. The solution was then adjusted to pH 11 with sodium carbonate and the resulting white solid was filtered, washed with water, then dried in vacuo to afford the title compound as a solid.
