Procedure

To a suspension of 1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carboxylic acid (360 mg, 1.4 mmol) in DMF (4 mL) was added DIPEA (487 μL, 2.8 mmol). After 10 minutes, HATU (638 mg, 1.68 mmol) was added to the brown solution. After 10 minutes, a solution of 4-((S)-1-amino-propyl)-2-carbamoyl-piperidine-1-carboxylic acid benzyl ester (0.45 g, 1.4 mmol) in DMF (4 mL) and DIPEA (244 μL, 1.4 mmol) was added resulting in a clear solution. After 18 hours, the reaction was diluted with EtOAc (200 mL), washed with NH4Cl (50 mL), water (50 mL), brine, dried over sodium sulfate, filtered and concentrated. The residue was purified by silica gel chromatography eluting with a gradient of 0-6% MeOH in DCM to afford 2-carbamoyl-4-((S)-1-{[1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carbonyl]-amino}-propyl)-piperidine-1-carboxylic acid benzyl ester as a light brown foam.
