Reaction Steps
Hydroquinone (18 g, 163.5 mmol), 4-fluorobenzonitrile (10 g, 81.75 mmol) and potassium carbonate (23 g, 163.5 mmol) were heated to 150° C. in dimethylformamide (40 mL) for 6 hours. The cooled mixture was diluted with water and 1 N hydrochloric acid and extracted with ethyl acetate. The separated organic layer was dried over sodium sulfate, filtered and concentrated. The crude product was chromatographed yielding 8 g of the title compound. MS (m/z, APCI): 210 [M−H]−.
