Vorschrift

A mixture of 2-chloromethyl quinoline (0.05 mol), phenol (0.055 mol), finely powdered potassium carbonate (0.055 mol), cesium carbonate (0.005 mol) and sodium iodide (0.0025 mol) in acetone was refluxed for about 4 hours. The reaction mixture was cooled to room temperature and filtered and the filtrate was concentrated and dissolved in ether. The ether solution was washed thoroughly with lN NaOH solution, water and brine. After drying the ether solution over anhydrous magnesium sulfate, and filtering off the drying agent, the solvent was evaporated off to leave the crude product which was crystallized from hexane and ether to yield the desired compound as a light yellow solid, m.p. 79.5°-80.5° C.
