Reaction Steps

A mixture of 1-(5-chloro-6-fluoro-2-pyridyl)-6-(5-ethyl-3-pyridyl)pyrazolo[4,3-c]pyridine (0.155 mmol; 54.9 mg), tert-butyl N-[(3S)-3-piperidyl]carbamate (0.466 mmol; 93.2 mg), and N-Methylmorpholine (1.55 mmol; 159 mg; 0.172 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 and dried on high vacuum to afford tert-butyl N-[(3S)-1-[3-chloro-6-[6-(5-ethyl-3-pyridyl)pyrazolo[4,3-c]pyridin-1-yl]-2-pyridyl]-3-piperidyl]carbamate (66.6 mg, 80%), which was used without further purification.
