실험 절차

To a solution of (2S,4S)-tert-butyl 4-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-(((R)-1,2,3,4-tetrahydronaphthalen-1-yl)carbamoyl)pyrrolidine-1-carboxylate (6.70 g, 11.5 mmol) in CH2Cl2 (50 mL) at rt was added TFA (15 mL) dropwise. The reaction mixture was stirred at rt for 2 h, and then concentrated in vacuo. The residue was dissolved in CH2Cl2 (200 mL) and washed with aq. K2HPO4 solution (50 mL). The organic layer was dried over MgSO4, filtered and concentrated in vacuo to give crude (9H-fluoren-9-yl)methyl ((3S,5S)-5-(((R)-1,2,3,4-tetrahydronaphthalen-1-yl)carbamoyl)pyrrolidin-3-yl)carbamate (5.54 g, 100%), which was used directly in the next step.
