실험 절차

3-(2-Isopropoxy-phenoxy)-propylamine. To a solution of 2-[3-(2-isopropoxy-phenoxy)-propyl]-isoindole-1,3-dione in EtOH (6 mL) was added hydrazine (0.448 g, 14.0 mmol), and the reaction mixture was heated to 50° C. for 30 min. The solvent was removed under reduced pressure, and the crude residue was partitioned between CH2Cl2 (50 mL) and H2O (50 mL). The aqueous layer was extracted with CH2Cl2 (3×50 mL), and the combined organic layers were washed with brine, dried (MgSO4), filtered, and concentrated under reduced pressure. The resulting residue was purified by column chromatography (20-50% EtOAc/hexanes) to provide the desired product (0.267 g, 45%). MS (ESI): mass calculated for C12H19NO2, 209.29; m/z found, 210.2 [M+H]+. 1H NMR (400 MHz, CDCl3): 6.91-6.83 (m, 4H), 4.46 (hept, J=6.1 Hz, 1H), 4.07 (t, J=5.9 Hz, 2H), 2.97 (t, J=6.5 Hz, 2H), 1.99 (quint, J=6.2 Hz, 2H), 1.32 (d, J=6.1 Hz, 6H).
