Procedure

cis-3,4-Dihydroxypyrrolidine (Preparation 23, 9 mg, 0.087 mmol) was added to a solution of 3-(S)-[(5-chloro-1H-pyrrolo[2,3-c]pyridine-2-carbonyl)amino]-2-(S)-hydroxy-4-phenylbutyric acid (EXAMPLE 124, 30 mg, 0.080 mmol), HOBt (14 mg, 0.091 mmol), DIPEA (31 μL, 0.18 mmol) and EDCI (18 mg, 0.094 mmol) in DMF (3 mL). After stirring for 12 h the mixture was added to diluted brine (100 mL, water/brine: 1/1). Extraction with ethyl acetate (4×25 mL), washing of the combined extracts with brine (50 mL) and drying (MgSO4) gave, after concentration, a residue which was purified by preparative LCMS to give the title compound as a colourless solid. m/z (ES+)=459.29 [M+H]+; RT=2.87 min.
