Column chromatography using a solvent mixture (hexane/ethyl acetate=10/1, Rf=0.4) afforded N-(4-chlorophenyl)benzylamine (182 mg, 84% isolated yield) as light yellow liquid. The spectral data (1H NMR) matched with the literature references and GC analysis indicated >95% purity. See Burton, R. D.; Bartberger, M. D.; Zhang, Y.; Eyler, J. R.; Schanze, K. S. J. Am. Chem.
