Reaction Steps
The general procedure under argon was followed using copper(I) iodide (19 mg, 0.10 mmol), K3PO4 (425 mg, 2.00 mmol), N-methylbenzylamine (155 μL, 1.20 mmol), iodobenzene (112 μL, 1.00 mmol), ethylene glycol (111 μL, 2.00 mmol) and 1-butanol (1.0 mL) at 90° C. Column chromatography using a solvent mixture (hexane/ethyl acetate=20/1, Rf=0.5) afforded N-methyl-N-phenylbenzylamine (146 mg, 74% isolated yield) as colorless liquid. The spectral data (1H NMR) matched with the literature references and GC analysis indicated >95% purity. See Brenner, E.; Schneider, R.; Fort, Y. Tetrahedron 1999, 55, 12829-12842.
