Reaction Steps

8-(Benzyloxy)-2-chloroquinoline (5.0 g, 18.5 mmol), 7-(2-methoxyethoxy)-imidazo[1,2-a]pyridine (3.56 g, 18.5 mmol), Pd(PPh3)4 (1.07 g, 0.927 mmol), K2CO3 (5.12 g, 37.1 mmol), and Pd(OAc)2 (0.208 g, 0.927 mmol) were added into dioxane (74.1 ml, 18.5 mmol) and water (0.735 ml, 40.8 mmol) and heated to 100° C. overnight under nitrogen. The reaction was diluted with DCM and carbon (5 g) was added, followed by filtration. The filtrate was concentrated and then triturated with 1:1 EtOAc/MTBE (30 mL). The resulting solids were allowed to stir for 5 hours and then filtered to isolate of the desired product as a solid (5.4 g, 69% yield).
