Procedure

n-Propylamine (16 μL, 0.19 mmol) was added to a solution of 3-(S)-[(5-chloro-1H-pyrrolo[2,3-c]pyridine-2-carbonyl)amino]-2-(R)-hydroxy-4-phenylbutyric acid (EXAMPLE 44, 40 mg, 0.11 mmol), HOBt (16.4 mg, 0.11 mmol), DIPEA (41 μL, 0.24 mmol) and EDCI (25 mg, 0.13 mmol) in DMF (3 mL). After stirring for 72 h at room temperature the solvent was removed in vacuo and the remaining residue was purified by preparative LCMS to give the title compound as colourless solid. m/z (ES+)=415.34 [M+H]+; RT=3.10 min.
