실험 절차
To a solution of 3-(4-chloro-phenyl)-prop-2-ynylamine (2.5 g) in 50 mL of THF at room temperature was added a 1M solution of LiAlH4 in THF (30 mL) and the mixture was heated at reflux for 1 hr. It was cooled to room temperature, and to it was successively added 1.1 mL H2O, 1.1 mL of 15% aq. NaOH and 3.4 mL H2O. The precipitated solid was filtered off and the filtrate was concentrated and purified by chromatography to provide 1.45 g of 3-(4-chloro-phenyl)-allylamine. NMR (400 MHz, CDCl3) 7.26-7.21 (m, 4H), 6.42 (dt, J=16.0, 1.6 Hz, 1H), 6.29-6.22 (m, 1H), 3.44 (dd, J=5.6, 1.6 Hz, 2H)
