Procedure

1-Benzyloxy-4-bromo-2-tert-butyl-benzene made in example 47B (319 mg, 1 mmol), zinc cyanide (129 mg, 1.1 mmol) and Pd(PPh3)4 (34.5 mg, 0.03 mmol) were mixed in 4 mL of DMF then the mixture was heated to 175 ° C. in a microwave reactor (Emrys Optimizer by Personal Chemistry) for 5 minutes. The mixture was cooled to room temperature, and then water and EtOAc were added. The EtOAc extracts were dried over Na2SO4, concentrated and the resulting residue was purified by flash chromatography (5–10% EtOAc/Hexanes) to give the desired nitrile (64 mg). MS (DCI) m/z 238 (M+H)+.
