실험 절차

To a solution of (2R,4S,5S)-5-amino-4-hydroxy-2-methyl-6-phenylhexanoic acid (3,3-dimethylbutyl)amide (D2) (46 mg, 0.145 mmol) in DMF (2 ml) was added iPr2NEt (61 μl, 0.348 mmol) followed by 3,5-bis-2-oxopyrrolidin-1-yl)benzoic acid (D8) (50 mg, 0.174 mmol) and HATU (77 mg, 0.203 mmol). The reaction mixture was stirred at room temperature for 6 hours. The solvent was evaporated to dryness and the residue was partitioned between 0.5 M HCl and DCM. The organic phase was separated and washed with NaHCO3, brine and dried over MgSO4, filtered and evaporated to afford the crude product (61 mg) as yellow oil. The product was triturated in petroleum/diethylether which yielded E5 (55 mg) as a yellow solid.
