Procedure

To a solution of (S)-2-amino-3-pyridin-3-yl-1-pyrrolidin-1-ylpropan-1-one hydrochloride (Preparation 54, 239 mg, 0.94 mmol) in DMF (5 mL) was added DIPEA (0.60 mL, 3.28 mmol), 5-chloro-1H-pyrrolo[2,3-c]pyridine-2-carboxylic acid (Preparation 18, 184 mg, 0.94 mmol) and TBTU (330 mg, 1.03 mmol). The reaction mixture was stirred at rt for 16 h. The solvent was removed in vacuo and the residue partitioned between ethyl acetate (100 mL) and sodium hydroxide solution (2×100 mL, 1N). The organic phase was dried (MgSO4) and evaporated to dryness give the title compound as a brown solid. δH (CD3OD): 1.74-1.94 (4H, m), 3.12-3.39 (4H, m), 3.41-3.48 (1H, m), 3.69-3.75 (1H, m), 5.07-5.12 (1H, m), 7.16 (1H, s), 7.34-7.39 (1H, m), 7.67 (1H, s), 7.79-7.83 (1H, m), 8.37-8.42 (1H, m), 8.45-8.51 (1H, m), 8.56 (1H, s); m/z (ES+)=398 [M+H]+.
