実験手順
To a solution of 3-Bromo-6-trifluoromethyl-imidazo[1,2-a]pyridine (1 eq, 2.9 mmol, 0.77 g), 2-chloropyrid-4-yl boronic acid (1.05 eq, 3.05 mmol, 0.478 g), Na2CO3 (2 eq, 5.81 mmol, 0.616 g) in dioxane (45 ml) and water (13.5 ml), under an inert atmosphere of argon is added bis(triphenylphosphine)palladium II chloride (0.1 eq, 0.03 mmol, 200 mg). The reaction mixture is heated at 95° C. for 16 hours. The mixture is diluted with H2O (50 ml) and extracted with EtOAc. The combined organic portions are washed with brine, dried (MgSO4) and concentrated in vacuo. The residue is purified by chromatography on silica eluting with 0-10% MeOH in EtOAc to afford the title compound; [M+H]+=297/299.
