Reaction Steps

N,N-Dimethylhydrazine (2.0 equiv., 1.0 mmol, 0.075 mL), bromobenzene (1 equiv., 0.5 mmol, 0.05 mL), Pd2(DBA)3 (0.025 equiv., 0.0125 mmol, 12 mg), BINAP (0.05 equiv., 0.025 mmol, 16 mg), LiOtBu (1.2 equiv., 0.6 mmol, 48 mg) and toluene (5 mL) were added to an oven dried test tube which was capped with a septum and purged briefly with argon (˜1 min.), and then heated to 80° C. under argon for 18 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 yellow oil (17 mg, 0.12 mmol, 24% yield).
