Reaction Conditions

Reaction Steps

A mixture of (4-bromo-2,6-difluorophenyl)methanol (1.12 g, 5.0 mmol), Pd(PPh3)4 (323 mg, 0.28 mmol) and zinc cyanide (587 mg, 5.0 mmol) was prepared in DMF (7 mL) under nitrogen atmosphere and heated at 90° C. for 18 hours. The mixture was diluted with DCM and water. The organic phase was passed through a hydrophobic frit and the solvent evaporated in vacuo. The residue was purified by flash chromatography (silica, iso-hexane/EtOAc) to afford the title compound. 1H NMR (CDCl3, 400 MHz) δ 7.28-7.21 (2H, m), 4.83 (2H, d, J=6.7 Hz), 1.95 (1H, t, J=6.7 Hz).
