The general procedure under argon or air was followed using copper(I) iodide (10 mg, 0.05 mmol), K3PO4 (425 mg, 2.00 mmol), benzylamine (131 μL, 1.20 mmol), 5-iodo-m-xylene (144 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=0.5) afforded 5-(N-benzyl)amino-m-xylene (177 mg, 84% isolated yield) as colorless liquid. The spectral data (1H NMR) matched with the literature references and GC analysis indicated >95% purity. See Wolfe, J. P.; Buchwald, S. L. J. Org. Chem. 2000, 65, 1144–1157.
