Procedure

5-Chloro-1H-pyrrolo[2,3-b]pyridine-2-carboxylic acid (Preparation 57, 50 mg, 0.25 mmol), 2-(S)-amino-3-(4-fluorophenyl)-1-(4-hydroxypiperidin-1-yl)propan-1-one hydrochloride (85 mg, 0.25 mmol) and DMTMM (85 mg, 0.31 mmol) were dissolved in ethanol (5 ml) and 4-methylmorpholine (31 μl, 0.28 mmol). The reaction mixture was stirred at rt for 16 h. The solvent was removed in vacuo and the residue partitioned between water (30 ml) and EtOAc (3×25 ml). The combined organics were dried (MgSO4), concentrated in vacuo and purified by chromatography on silica gel eluting with methanol:dichloromethane (1:19) to give the title compound as a beige solid. m/z (ES+)=445 [M+H]+; RT=3.31 min.
