Reaction Conditions

Reaction Steps

Potassium carbonate (0.239 g, 1.73 mmol) and (2-methoxypyridin-3-yl)boronic acid (0.162 g, 0.950 mmol) were added to a solution of 3-bromo-4-[(6-isobutoxypyridin-3-yl)oxy]benzonitrile (Preparation 6, 0.300 g, 0.864 mmol) in dioxane (10 mL). The reaction was degassed three times. Tetrakis(triphenylphosphine)palladium(0) (0.010 g, 0.009 mmol) was added and the mixture was degassed three times more. The mixture was heated at 60° C. for 24 hours, then allowed to cool to room temperature and filtered through arbocel, washing with DCM/MeOH (1/1, 50 mL). The combined filtrates were concentrated in vacuo. The residue was absorbed onto silica and purified by silica gel chromatography (Biotage®, SNAP cartridge 50 g, gradient from 5 to 10% EtOAc in heptane 6, then 10% EtOAc in Heptane) to yield the title compound as a solid (0.257 g).
