실험 절차
2-[1-(4-Chloro-3-fluoro-phenyl)-ethyl]-isoindole-1,3-dione (4.08 g, 13.4 mmol) was dissolved in THF (100 mL). Hydrazine (4 mL) was added. The reaction was stirred at 80° C. for 1 h. Then, the solvent was evaporated and the crude was chromatograph over silica gel using ethyl acetate as solvent to yield 2.0 g of 1-(4-chloro-3-fluoro-phenyl)-ehtylamine. 1H NMR (400 Hz, Cl3CD) δ 7.34 (t, J=7.97 Hz, 1H), 7.18 (dd, J=1.90, 10.25 Hz, 1H), 7.08 (dd, J=1.90, 7.97 Hz, 1H), 4.12 (m, 1H), 1.36 (d, J=6.64, 3H).
