70 °C

Into a reaction flask were added N-(3-bromo-5-methoxybenzyl)-2,5-dichloropyrimidin-4-amine (2.0 g, 5.5 mmol), 1,4-dioxane (30 mL), 3-(3-aminophenyl)propan-1-ol (1.2 g, 8.3 mmol, prepared according to Example 12, Step B), and p-toluenesulfonic acid monohydrate (0.12 g, 0.63 mmol). The mixture was heated at 70° C. over two days and NaHCO3 (saturated aqueous solution) was added. After removal of the organic solvent, the aqueous layer was extracted with methylene chloride twice. The combined organic layers were washed with water and brine successively, then dried (Na2SO4), filtered, and concentrated to give the desired product as a white powder (2.6 g, 99%). LCMS for C21H22BrClN4O2 (M+H)+: m/z=477.0, 479.0.
