실험 절차
To an oven-dried 150 mL round-bottomed flask charged with 3-(4-aminophenyl)propionic acid (Aldrich, 3.0 g, 18.16 mmol) was added THF (50 mL) and lithium aluminum hydride (Aldrich, 1.0M THF solution, 37 mL, 36.32 mmol) at 0° C. The reaction mixture was added Na2SO4.10H2O after 3 h until there was no visible bubbles. The liquid was filtered. The solid was washed with THF and CH2Cl2. The filtrate was dried over Na2SO4. After filtration and concentration in vacuo, the crude was purified by flash chomatography (7% MeOH—CH2Cl2) to provide the title product. MS (ESI): 152 (M+H)+.
