Reaktionsschritte

To a mixture of 6-(6-methylpyrazin-2-yl)-1H-pyrazolo[4,3-c]pyridine (0.468 mmol; 98.9 mg) and 2,6-difluoro-4-(oxetan-3-yl)pyridine (0.468 mmol; 80.1 mg) in DMF (5 mL) was added Cesium carbonate (0.562 mmol; 183 mg). The resulting mixture was stirred at room temperature. The mixture was filtered. The filtrate was partitioned between EtOAc and water. The organic layer was concentrated. The residue was purified on silica eluted with 0 to 6% MeOH in DCM to afford 1-[6-fluoro-4-(oxetan-3-yl)-2-pyridyl]-6-(6-methylpyrazin-2-yl)pyrazolo[4,3-c]pyridine as a white solid (63.2 mg, 31%).
