Procedure
A slurry of 2,6-difluorophenol (1.0 g, 8 mmol), potassium carbonate (3.29 g, 24.2 mmol) and 4-fluoro benzaldehyde (1.36 g 10.4 mmol) in dry DMF (50 mL) was stirred at 100° C. overnight under nitrogen atmosphere. After the reaction is completed it was cooled to room temperature and poured in to ice cold water. The mixture was extracted with ethyl acetate (100 mL×2). The combined organic layers were washed with water (50 mL×2), brine, then dried over anhydrous sodium sulphate and concentrated. The resulting residue was purified by column chromatography using 3% ethyl acetate in hexane to obtain the title compound.
