Reaction Steps

A solution containing 6-(6-ethylpyrazin-2-yl)-1-(6-fluoro-2-pyridyl)pyrazolo[4,3-c]pyridine (75 mg, 0.23 mmol) and tert-butyl N-[(3S)-3-piperidyl]carbamate (234 mg, 1.17 mmol) in methyl sulfoxide 2.0 mL was heated 95° C. The reaction was quenched with water then extracted with EtOAc. The organic layers was dried with sodium sulfate, filtered, and concentrated in vacuum. The crude product was purified by flash chromatography (EtOAc/Heptane eluted at 65% EtOAc) to give (S)-tert-butyl(1-(6-(6-(6-ethylpyrazin-2-yl)-1H-pyrazolo[4,3-c]pyridin-1-yl)pyridin-2-yl)piperidin-3-yl)carbamate (80 mg) in 68% yield.
