実験手順

To a mixture of 4-nitrophenol (10.0 g, 71.9 mmol), K2CO3 (19.9 g, 143.9 mmol) and KI (2.6 g, 15.8 mmol) in acetonitrile was added chloromethylbenzene (10.0 g, 79.1 mmol) at RT. The resultant mixture was heated to reflux for 3 h. After removal of the solvent, the residue was dissolved in EtOAc. The combined organic extracts were washed with brine, dried (Na2SO4), filtered and concentrated to afford 4-benzyloxynitrobenzene (14.9 g, 90% yield). 1H NMR (400 MHz, CDCl3): δ 8.20 (d, J=8.0 Hz, 2H), 7.43-7.37 (m, 5H), 7.03 (d, J=8.0 Hz, 2H), 5.17 (s, 2H).
