실험 절차
To a solution of cyclopropyl-(5-fluoro-2-nitrophenyl)amine (6.3 mmol) in EtOAc (60 mL) was added 10% Pd/C (150 mg) and the reaction mixture was stirred at RT under a hydrogen atmosphere for 5 h. The suspension was filtered through a pad of Celite® and the filtrate concentrated in vacuo to afford the title compound as a brown oil (1.1 g, quantitative). 1H NMR (CDCl3, 300 MHz): δ 6.76 (1H, dd, J=10.85, 2.76 Hz), 6.60 (1H, dd, J=8.38, 5.56 Hz), 6.34 (1H, td, J=8.45, 2.82 Hz), 4.15 (1H, br s), 3.03 (2H, br s), 2.45-2.36 (1H, m), 0.80-0.72 (2H, m), 0.56-0.49 (2H, m).
