실험 절차

To a stirred solution of 2-(3-(3-aminophenyl)propyl)isoindoline-1,3-dione (0.50 g, 1.78 mmol) in EtOH:H2O (9:1), 2,2-dipropyloxirane (0.45 g, 3.57 mmol) was added and the reaction mixture was stirred under reflux for 36 h. The reaction mixture was concentrated under reduced pressure. Purification by column chromatography (20% to 30% EtOAc—hexanes gradient) gave 2-(3-(3-(2-hydroxy-2-propylpentylamino)phenyl)propyl)isoindoline-1,3-dione as a yellow semisolid. Yield (0.22 g, 30%); 1H NMR (400 MHz, DMSO-d6) δ 7.86-7.81 (m, 4H), 6.92 (t, J=7.8 Hz, 1H), 6.45 (s, 1H), 6.41 (d, J=8.0 Hz, 1H), 6.37 (d, J=7.6 Hz, 1H), 4.89 (bs, 1H), 4.16 (s, 1H), 3.59 (t, J=7.2 Hz, 2H), 2.87 (d, J=5.2, 2H), 2.46-2.50 (m, 2H), 1.83-1.90 (quintet, J=7.2 Hz, 2H), 1.42-1.38 (m, 4H), 1.28-1.24 (m, 4H), 0.84 (t, J=7.2 Hz, 6H).
