반응 단계
650 mg (0.94 mmol) N-[(9H-fluoren-9-ylmethoxy)carbonyl]-N-methyl-L-valyl-N-[(3R,4S,5S)-1-tert.-butoxy-3-methoxy-5-methyl-1-oxoheptane-4-yl]-N-methyl-L-valinamide (intermediate 3) were absorbed by 5 ml dichlormethane, 5 ml trifluoroacetic acid were added and then stirred overnight at RT. Then, the mixture was evaporated in vacuum and the remaining residue was purified using HPLC. 430 mg (72% o. th.) of the title compound were obtained as a colorless foam.
