Reaction Steps

A mixture of 6-chloro-1-(6-fluoro-2-pyridyl)pyrazolo[4,3-c]pyridine (2.998 mmol; 745.3 mg), tert-butyl N-[(3S)-3-piperidyl]carbamate (4.496 mmol; 900.5 mg), and N-Methylmorpholine (8.993 mmol; 919 mg; 0.999 mL) in 1-methyl-2-pyrrolidinone (10 mL) in a sealed pressure vial was heated at 100° C. overnight. The mixture was poured into water. The precipitate was collect by filtration, then purified on silica eluted with 0 to 40% EtOAc in Heptane to afford tert-butyl N-[(3S)-1-[6-(6-chloropyrazolo[4,3-c]pyridin-1-yl)-2-pyridyl]-3-piperidyl]carbamate (1.0738 g, 84%).
