Procedure

The general procedure under argon was followed using copper(I) iodide (19 mg, 0.10 mmol), K3PO4 (425 mg, 2.00 mmol), benzylamine (131 μl, 1.20 mmol), 2-iodoanisole (130 μl 1.00 mmol), ethylene glycol (111 μl, 2.00 mmol) and 1-butanol (1.0 mL) at 100° C. Column chromatography using a solvent mixture (hexane/ethyl acetate=10/1, Rƒ=0.4) afforded N-(2-methoxyphenyl)benzylamine (149 mg, 70% isolated yield) as colorless liquid. The spectral data (1H NMR) matched with the literature references and GC analysis indicated >95% purity.
