실험 절차

2-[(4-Nitrophenoxy)methyl]pyridine (2.30 g, 10 mmol) was dissolved in ethanol (160 mL) and water (40 mL). NH4Cl (5.30 g) was added to the above mixture and heated to 70-80° C. To this reaction mixture was added iron powder (5.50 g) in portion wise manner under a vigorous stirring and the stirring was continued for 2 h. The reaction mixture was filtered through a Celite pad when hot and washed the filter bed with MeOH. The filtrate was concentrated, diluted with water, extracted with CH2Cl2 (3×75 mL), dried and concentrated to provide 2-[(4-aminophenoxy)methyl]pyridine as brown solid (1.735 g) in 86% yield. 1H NMR (CDCl3): δ 8.56 (m, 1H), 7.67 (m, 1H), 7.49 (d, 1H, J=7.8 Hz), 7.18 (m, 1H), 6.80 (d, 2H, J=8.7 Hz), 6.62 (d, 2H, J=8.7 Hz), 5.12 (s, 2H), 3.43 (br s, 2H); LCMS (m/z): 201 (MH+).
