الإجراء التجريبي

Phosphorus oxychloride (37.4 mL, 402 mmol) was added to 2-hydroxy-4-phenylquinoline and the mixture was heated to reflux for 4 hours. Upon cooling to room temperature, the mixture was added slowly to stirring ice water yielding a white precipitate. The mixture was extracted with methylene chloride, and the organic phases were combined, dried with magnesium sulfate, filtered and concentrated to yield 2-chloro-4-phenylquinoline.
