1,2-Diethylhydrazine dihydrochloride (1.2 equiv., 0.6 mmol, 97 mg), bromobenzene (1.0 equiv., 0.5 mmol, 0.05 mL), Pd(OAc)2 (0.05 equiv, 0.025 mmol, 6 mg), BINAP (0.05 equiv., 0.025 mmol, 16 mg), and NaOtBu (3.8 equiv., 1.9 mmol, 183 mg) and diisopropylamine (2 mL) were added to a flame dried test tube which was capped with a septum and purged briefly with argon (˜1 min.) and then heated to 80° C. for 4 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 (2% EtOAc/Hex) to give the title product as a viscous yellow oil (27 mg, 0.16 mmol, 33% yield).
