Reaction Conditions

Reaction Steps

Tetrakis(triphenylphosphine)palladium (1.16 g), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (2.48 g) and potassium carbonate (4.15 g) were added to a solution of 5-bromo-3-iodopyridin-2-amine (2.99 g) in 1,4-dioxane (40 ml) and water (10 ml) at room temperature. The reaction mixture was stirred at 100° C. overnight. The reaction mixture was concentrated under reduced pressure, and the residue was then purified by silica gel chromatography [chloroform:methanol=9:1 (v/v)] to give 2.48 g of the title compound as a solid.
