Reaction Steps

4-Fluorophenylhydrazine hydrochloride (1.2 equiv., 0.6 mmol, 98 mg), 4-bromobiphenyl (1.0 equiv., 0.5 mmol, 117 mg), Pd(OAc)2 (0.05 equiv., 0.025 mmol, 6 mg), BINAP (0.05 equiv., 0.025 mmol, 16 mg), NaOtBu (1.4 equiv., 0.7 mmol, 67 mg) and diisopropylamine (2 mL) were added to an oven dried test tube which was capped with a septum and purged briefly with argon (a 1 min.), and then heated to 50° C. under argon for 7 hours. The reaction was then cooled to room temperature, diluted with Et2O (2 mL), filtered through Celite and concentrated under vacuum. The crude mixture was purified by flash column chromatography (10% EtOAc/Hex) to give the title product as a white solid (110 mg, 0.39 mmol, 79% yield).
