Reaction Steps

The general procedure under argon or air was followed using copper(I) iodide (10 mg, 0.05 mmol or 2.0 mg, 0.01 mmol), K3PO4 (425 mg, 2.00 mmol), benzylamine (131 μl, 1.20 mmol), 3-bromoiodobenzene (128 μL, 1.00 mmol), ethylene glycol (111 μL, 2.00 mmol) and 2-propanol (1.0 mL). Column chromatography using a solvent mixture (hexane/ethyl acetate=20/1, Rf=0.4) afforded N-(3-bromophenyl)benzylamine (217 mg, 83% isolated yield) as colorless liquid. The spectral data (1H NMR) matched with the literature references and GC analysis indicated >95% purity. See Beletskaya, I. P.; Bessmertnykh, A. G.; Guilard, R. Synlett 1999, 1459-1461.
