Water → tert-butyl N-[(3S)-1-[3-chloro-6-[6-(6-methylpyrazin-2-yl)pyrazolo[4,3-c]pyridin-1-yl]-2-pyridyl]-3-piperidyl]carbamate

Participants

Reaction Steps

A mixture of 1-(5-chloro-6-fluoro-2-pyridyl)-6-(6-methylpyrazin-2-yl)pyrazolo[4,3-c]pyridine; (0.6372 mmol; 217.1 mg), tert-butyl N-[(3S)-3-piperidyl]carbamate (1.912 mmol; 382.9 mg), and N-Methylmorpholine (3.186 mmol; 326 mg; 0.354 mL) in 1-methyl-2-pyrrolidinone (3 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 6% MeOH in DCM to afford tert-butyl N-[(3S)-1-[3-chloro-6-[6-(6-methylpyrazin-2-yl)pyrazolo[4,3-c]pyridin-1-yl]-2-pyridyl]-3-piperidyl]carbamate (229.4 mg, 69%).
