Reaction Steps

4-Chloro-2-fluorobenzonitrile (0.35 g, 2.2 mmol), 3-hydroxy-2-propoxybenzaldehyde (0.40 g, 2.2 mmol) and cesium carbonate (0.72 g, 2.2 mmol) were heated with stirring in dry DMF (4 mL) at 50° C. for 19 h. The reaction mixture was cooled, poured into water and extracted with ethyl acetate. The ethyl acetate layer was separated, washed with 1N sodium hydroxide solution (2×), water (1×), brine (1×), and dried over MgSO4. After filtration, the solvent was removed in vacuo to yield 4-chloro-2-(3-formyl-2-propoxyphenoxy)-benzonitrile (0.69 g, 98%) as a brown oil, which was used without further purification.
