反応手順

To suspension of LiAlH4 (0.5 g, 1.3 mmol) in diethyl ether (25 mL) was added 3-bromocinnamic acid (83, 1.0 g, 4 mmol), in portions, at RT. The resulting suspension was stirred for 3 hours. The reaction was quenched by the successive addition of 15% aq. NaOH solution (1 mL) and water. The resulting white suspension was filtered through a pad of Celite. The filter cake was washed with ether and then ethyl acetate. The filtrate was concentrated to afford crude 8 as yellow oil. Yield (0.7 g, 74%). 1H NMR (400 MHz, CDCl3) δ 7.10-7.35 (m, 4H), 3.65 (t, J=6.5 Hz, 2H), 2.68 (t, J=7.8 Hz, 2H), 1.82-1.91 (m, 2H).
