2-(3-Bromo-4-fluorophenyl)acetic acid (64 g, 275 mmol) was diluted with DMF (400 mL) followed by the addition of Cu(I)CN (49 g, 549 mmol). The reaction was heated to 130° C. and stirred for 12 hours. The reaction was allowed to cool and diluted with ethyl acetate and water, and the mixture was filtered. The organic layer was washed with water, 1N HCl, water and the brine. The organic layer was dried over MgSO4, filtered and concentrated to yield 2-(3-cyano-4-fluorophenyl)acetic acid (36 g, 73% yield) as light yellow oil that solidified to a light yellow solid.
