実験手順

Z-Gly-LeuOH was made by mixed anhydride coupling of Z-GlyOH and LeuOBzl tosylate, followed by NaOH hydrolysis of the benzyl ester. To a solution of Z-Gly-LeuOH (0.223 g, 0.69 mmol) in THF (4 mL) at -20° C. was added NMM (76 uL, 0.69 mmol), followed by IBCF (90 uL, 0.69 mmol). After 10 minutes, a precooled solution of PheCH2F hydrochloride (0.15 g, 0.69 mmol) in DMF (1 mL) was added, followed by a second equivalent (76 uL, 0.69 mmol) of NMM. After 30 minutes of stirring, the mixture was quenched with 1M HCl (5 mL), extracted with ethyl acetate (20 mL), washed with saturated aqueous NaHCO3 (6 mL), brine (5 mL), dried over MgSO4, filtered, and evaporated to dryness. The residue was crystallized from ether/hexane to give 0.18 g (54%) of Z-Gly-Leu-PheCH2F.
