Reaction Steps
Prepared according to procedure Y by stirring 4-chloro-5,7-difluoro-2-(2-methoxypyridin-4-yl)-3-methylquinoline (50 mg, 0.16 mmol), 6′-morpholino-1′,2,2′,3,5,6-hexahydrospiro[pyran-4,3′-pyrrolo[3,2-b]pyridine] (42.9 mg, 0.16 mmol), sodium tert-butoxide (33.0 mg, 0.34 mmol), XPhos precatalyst (23.0 mg, 0.031 mmol), and toluene (1.7 mL) at 85° C. for 6 h.
