Column chromatography using a solvent mixture (hexane/ethyl acetate=10/1, Rf=0.4) afforded N-(3-methoxyphenyl)benzylamine (171 mg, 80% isolated yield) as white solid. The spectral data (1H NMR) matched with the literature references and GC analysis indicated >95% purity. See Ali, M. H.; Buchwald, S. L. J. Org. Chem. 2001, 66, 2560-2565.
