PdCl2(dppf)-CH2Cl2 adduct (0.012 g, 0.015 mmol), N-(3-bromo-5-methylphenyl)-4-cyclopropylpyrimidin-2-amine (0.036 g, 0.120 mmol), [2-(3-ethoxy-3-oxopropyl)pyrimidin-5-yl]boronic acid (0.022 g, 0.1 mmol), and sodium carbonate (100 μL, 0.200 mmol) were suspended in dioxane (750 uL) and heated to 100° C. for 14 hours. Si-dimercaptotriazine (0.185 g, 0.1 mmol) was added to the reaction mixture. The vessel was sealed and allowed to stir at room temperature for 4 hours. The mixture was filtered, washing with DMSO (1 mL) and concentrated under reduced pressure at 40° C. The residue, dissolved in 2 mL of DMSO, was purified by mass triggered reverse phase HPLC to afford ethyl 3-(5-{3-[(4-cyclopropylpyrimidin-2-yl)amino]-5-methylphenyl}pyrimidin-2-yl)propanoate.
