実験手順

A mixture of 2-(3-(3-(2-hydroxy-2-propylpentylamino)phenyl)propyl)isoindoline-1,3-dione (0.22 g, 0.71 mmol) and hydrazine hydrate (0.1 ml, 1.6 mmol) in ethanol was stirred at room temperature for 24 hours. The solvent was evaporated under reduced pressure. Purification by column chromatography (5% to 10% MeOH—CH2Cl2 gradient) gave 4-((3-(3-aminopropyl)phenylamino)methyl)heptan-4-ol as a light yellow semisolid. Yield (0.06 g, 18%); 1H NMR (400 MHz, DMSO-d6) δ 6.93 (t, J=7.6 Hz, 1H), 6.44-6.41 (m, 2H), 6.35 (d, J=7.6 Hz, 1H), 4.92 (t, J=5.2 Hz, 1H), 4.19 (bs, 1H), 2.87 (d, J=5.2 Hz, 2H), 2.54-2.50 (m, 2H), 2.44 (t, J=7.6 Hz, 2H), 1.55-1.62 (quintet, J=7.2 Hz, 2H), 1.42-1.33 (m, 4H), 1.32-1.27 (m, 4H), 0.85 (t, J=7.2 Hz, 6H); RP-HPLC (Method 3) tR=4.44 min, 97.48% (AUC); ESI MS m/z 279.31 [M+H]+.
