実験手順

To a solution of (S)-3-[(5-chloro-1H-pyrrolo[2,3-c]pyridine-2-carbonyl)amino]-2-(R)-hydroxy-4-phenylbutyric acid (EXAMPLE 44, 50 mg, 0.13 mmol), cis-3,4-dihydroxypyrrolidine (Preparation 23, 15 mg, 0.15 mmol) and HOBt (27 mg, 0.20 mmol) in DMF (5 mL), was added DIPEA (47 μL, 0.27 mmol). After stirring for 5 min, EDCI (28 mg, 0.15 mmol) was added and the reaction stirred at rt for 72 h. The solvent was removed in vacuo and the residue partitioned between water (30 mL) and ethyl acetate (3×30 mL). The combined organic fractions were dried (MgSO4), concentrated in vacuo and the residue purified by chromatography on silica gel eluting with methanol/dichloromethane (1:9) to give the title compound as a white solid. m/z (ES+)=459 [M+H]+. RT=3.07 min.
