To a solution of 2-bromonaphthalene (5.0 g) and tetrakis(triphenylphosphine)palladium(0) (0.56 g) in toluene (50 ml) was added a solution of dihydroxy(3-nitrophenyl)borane (4.44 g) in methanol and 2M sodium carbonate solution in water (12 ml). The resulting mixture was stirred at 80° C. for 4 hours and extracted with ethyl acetate. After evaporation of the solvent, the crude residue was crystallized from hexane to give 3-(2-naphthyl)-1-nitrobenzene (5.4 g).
