실험 절차

To tert-butyl (2R,5S)-2-[2-(2-aminophenyl)ethyl]-5-({[tert-butyl(dimethyl)silyl]oxy}methyl)morpholine-4-carboxylate (1 eq.) in DMF (0.15 M) at rt was added N-(methoxycarbonyl)-β-phenyl-L-phenylalanine (1.1 eq.), HATU (1.4 eq.) and 2,6-lutidine (3 eq.). The reaction mixture was stirred at rt for 16 h and diluted with EtOAc and saturated aqueous NaHCO3. The aqueous layer was extracted with EtOAc. The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated. The crude product was purified by automated SiO2 flash chromatography system using solvent gradient of 10% to 100% EtOAc/Hex to afford the desired compound.
