실험 절차

A mixture of 6-(6-methylpyrazin-2-yl)-1H-pyrazolo[4,3-c]pyridine (0.49711 mmol; 105 mg), tert-butyl N-[(3S)-1-(6-bromo-4-methyl-3-oxo-pyrazin-2-yl)-3-piperidyl]carbamate (0.6016 mmol; 233 mg), N,N′-Dimethylethylenediamine (0.049711 mmol; 4.382 mg; 0.00495 mL), copper iodide (0.49711 mmol; 95.629 mg), and potassium carbonate (0.99422 mmol; 138.79 mg) in 1,4-dioxane (10 ml) was purged with argon, then sealed and stirred at 100° C. overnight. The mixture was cooled to room temperature, and then filtered through Celite. The filtrate was concentrated; the residue was purified on silica eluted with 0 to % MeOH in DCM to afford tert-butyl N-[(3S)-1-[4-methyl-6-[6-(6-methylpyrazin-2-yl)pyrazolo[4,3-c]pyridin-1-yl]-3-oxo-pyrazin-2-yl]-3-piperidyl]carbamate (181.4 mg, 70%).
