4-Bromo-2-fluorophenol (10 ml, 91 mmol) and 9.85 g (0.11 mol) of CuCN were combined in 75 ml of NMP with stirring under nitrogen, and the mixture was heated at 150° C. for 5 h. The mixture was diluted with 200 ml of ether, stirred, and decanted. The residue was diluted again with 200 ml of ether, heated, and decanted. The combined decantates were washed with water, 1N HCl solution, water, and brine, and dried over magnesium sulfate. The organic solution was concentrated in vacuo to provide 12 g of a white solid which was triturated in carbon tetrachloride and filtered to afford 7.29 g (72.1%) of the title compound.
