Reaction Steps
The general procedure under argon was followed using copper(I) iodide (10 mg, 0.05 mmol), K3PO4 (425 mg, 2.00 mmol), benzylamine (131 μL, 1.20 mmol), 4-chloroiodobenzene (239 mg, 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=10/1, Rƒ=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.
