Reaction Steps

To a solution of 1,4-dibromonaphthalene (500 mg, 0.002 mol), Pyrrolidine (0.18 mL, 0.0021 mol), (R)-(+)-2,2′-Bis(diphenylphosphino)-1,1-binaphthyl (0.022 g, 0.000035 mol), Sodium tert-butoxide (0.24 g, 0.0024 mol) in Toluene (5.00 mL, 0.0469 mol) was added Tris(dibenzylideneacetone)dipalladium(0) (0.008 g, 0.000009 mol), and the mixture was heated at 70° C. overnight. The reaction was cooled, quenched by addition of water and the mixture was extracted with DCM (3×), washed with water, brine, dried (Na2SO4), filtered and concentrated. The residue was purified by flash chromatography (0 to 25% hexanes/DCM) to obtain 400 mg (80%). Reference: Jean, L.; Rouden, J.; Maddaluno, J.; Lasne, M-C. J. Org. Chem. 2004, 69, 8893-8902.
