실험 절차
3-(4-Nitrophenyl)propionitrile (740 mg, 4.2 mmol) was dissolved in methanol (100 mL), 10% Pd/C was added and the mixture was shaken under a hydrogen atmosphere (50 psi) at room temperature for 30 minutes. The mixture was filtered through Celite, and washed with 20 mL of methanol. The combined organic solvent was concentrated under reduced pressure to give crude materials which was further purified by flash column chromatography (Ethyl acetate:Hexanes 1:1) to yield 520 mg of 3-(4-Aminophenyl)propionitrile as a light yellow oil. 1H NMR (DMSO-d6): δ 6.91-6.88 (d, J=9.0 Hz, 2H), 6.49-6.46 (d, J=9.0 Hz, 2H), 4.92 (s, 2H), 2.66 (s, 4H).
