Procedure

A solution of potassium carbonate (0.35 g, 2.5 mmol) in water (2 mL) was added to a mixture of methyl 2-[(4-bromo-2-fluorobenzoyl)amino]propanoate (0.5 g, 1.6 mmol), 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-amine (0.28 g, 1.3 mmol), and tetrakis(triphenylphosphine)palladium (0.07 g, 0.06 mmol) in toluene (4 mL) and ethanol (2 mL). The resulting mixture was heated at 120° C. for 15 min. The reaction mixture was extracted with ether (3×10 mL) to remove impurity. The aqueous layer was adjusted to pH 7 with aqueous HCl and purified by RP-HPLC (pH 10) to afford the desired product (0.40 g, 100%). LCMS: (M+H)=305.0.
