실험 절차

N-Fmoc-2-(trans-Dec-4-en-1-ylamino)acetaldehyde dimethyl acetal (5 g, 10.7 mmol) was mixed with 30 mL of TFA and stirred at room temperature for 30 minutes. The reaction was poured into water (140 mL) and centrifuged to obtain a clear oil. The supernatant was decanted and the oil was mixed with 40 mL of water and centrifuged again. The supernatant was again decanted and the oil was dissolved in dichloromethane (100 mL), dried over MgSO4, filtered, and concentrated under reduced pressure to obtain 5.2 g (12.3 mmol) of N-Fmoc-2-(trans-Dec-4-en-1-ylamino)acetaldehyde as a clear oil.
