A mixture of 4-(5-chloro-2-(6-methoxypyridin-3-ylamino)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (160 mg, 0.274 mmol), 2-(dicyclohexylphosphino)-2′,4′,6′,-tri-i-propyl-1,1′-biphenyl (X-Phos, 13.06 mg, 0.027 mmol), cesium carbonate (268 mg, 0.822 mmol), potassium 1-methyl-4-trifluoroboratomethylpiperazine (Frontier Scientific Co., 66.3 mg, 0.301 mmol) and palladium acetate (3.08 mg, 0.014 mmol) was purged with argon. The mixture was then treated with THF (1.0 mL) and water (0.1 mL) and heated under microwave irradiation at 140° C. for 30 min. The mixture was filtered through a short path of Celite® (diatomaceous earth), washed with EtOAc (×3), and concentrated. The crude product was adsorbed onto a plug of silica gel and chromatographed through a Redi-Sep pre-packed silica gel column (pure DCM to 5% MeOH in DCM) to give N,N-bis(4-methoxybenzyl)-4-(2-(6-methoxypyridin-3-ylamino)-5-((4-methylpiperazin-1-yl)methyl)pyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (161 mg, 0.243 mmol, 89% yield) as a yellow syrup. m/z (ESI, +ve ion) 662.0 (M+H)+.
