The general procedure under argon was followed using copper(I) iodide (10 mg, 0.05 mmol), K3PO4 (425 mg, 2.00 mmol), (α-methylbenzylamine (155 μL, 1.20 mmol), iodobenzene (112 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, Rƒ=0.5) afforded N-(phenyl)-α-methylbenzylamine (144 mg, 73% isolated yield) as colorless liquid. HPLC conditions: (column: Daicel OD-H; solvent: 10% PrOH in hexane; flow rate: 0.7 mL/min; UV lamp: 254 nm; retention time: 6.01, 6.78 min). The spectral data (1H NMR) matched with the literature references and GC analysis indicated >95% purity. See Kainz, S.; Brinkmann, A.; Leitner, W.; Pfaltz, A. J. Am. Chem. Soc. 1999, 121, 6421-6429.
