실험 절차

To a solution of (3R,5S)-5-(methoxycarbonyl)pyrrolidin-3-yl 4-vinyl-1,3-dihydro-2H-isoindole-2-carboxylate hydrochloride (5.0 g, 14.2 mmol) and N-{[(2,2-dimethylhex-5-enyl)oxy]carbonyl}-3-methyl-L-valine (4.0 g, 14.2 mmol) in DMF (20 ml) at RT was added DIPEA (2.5 mL, 14.2 mmol), EDC (5.5 g, 28.4 mmol), and HOAt (1.9 g, 14.2 mmol). After 18 h the reaction mixture was poured into Et2O, and extracted with 1 N HCl. The aqueous layer was extracted with EtOAc, and the combined organic layers were washed with 1 N HCl, water, NaHCO3, and brine. The organic layer was dried over MgSO4 and the solvent was removed in vacuo. The crude product was purified on silica (30% EtOAc in hexanes) to yield 4.2 g of the title compound as a thick oil. LRMS (ESI) m/z 584.4 [(M+H)+; calcd for C32H46N3O7: 584.3].
