実験手順
A mixture of TEA (55.9 ml, 401 mmol), (4-methoxyphenyl)methanamine (50 g, 364 mmol) and 2-bromoacetonitrile (43.7 g, 364 mmol) in THF (500 ml) was stirred at about 10° C. for about 12 h in a 500 ml round-bottomed flask. The reaction was filtered through a pad of silica gel. The crude material was deposited onto silica gel, loaded onto a silica gel column and eluted with Hex/EtOAc (1:1) to afford the title compound (49 g, 278 mmol, 76% yield). 1H-NMR (CDCl3, 400 MHz): δ=3.55 (s, 2H), 3.81 (s, 3H), 3.87 (s, 2H), 6.88 (d, 2H, J=8.4 Hz), 7.26 (d, 2H, J=8.0 Hz)
