실험 절차
A solution of (S)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-N-undecylsuccinamic acid tert-butyl ester (113 mg, 0.2 mmol) in TFA (2 ml) was stirred at room temperature for 30 min. After completion of the reaction, TFA was removed by evaporation in vacuo. Purification of the residue by silica gel column chromatography (using dichloromethane:methanol=9:1 as an eluent) gave (S)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-N-undecylsuccinamic acid (101 mg, 99% yield) as a colorless amorphous solid.
