A mixture of (4-bromo-2-methylphenyl)methanol (603 mg, 3.0 mmol), Pd2(dba)3 (110 mg, 0.12 mmol), S-Phos (99 mg, 0.24 mmol) and zinc cyanide (421 mg, 3.6 mmol) was prepared in a mixture of DMF/water (99:1, 5 mL) under nitrogen atmosphere and heated at 130° C. for 30 minutes under microwave irradiation. The suspension was filtered through a Celite pad and the filter-cake washed with EtOAc. The filtrate was washed with water and brine. The organic phase was passed through a hydrophobic frit and the solvent evaporated in vacuo. The residue was purified by flash chromatography (silica, petrol ether/EtOAc) to give the title compound. 1H NMR (CDCl3, 400 MHz) δ 7.58-7.48 (2H, m), 7.44 (1H, s), 4.75 (2H, d, J=5.5 Hz), 2.33 (3H, s), 1.85-1.78 (1H, m).
