Procedure

To a solution of 2,5-dichloro-N-[2-(3-methoxyphenyl)ethyl]pyrimidin-4-amine (0.50 g, 1.7 mmol) (prepared according to Example 8, Step A) and 3-(3-aminophenyl)propan-1-ol (0.34 g, 2.3 mmol) in 1,4-dioxane (14.3 mL) was added p-toluenesulfonic acid monohydrate (0.12 g, 0.61 mmol). The mixture was heated at 100° C. for 16 hours and the reaction was complete. To the mixture was added NaHCO3 aqueous solution (saturated). The organic solvent was removed under vacuum. Water and EtOAc were added to the residue. The aqueous layer was extracted with EtOAc twice. The combined organic layers were dried over Na2SO4, filtered, and concentrated (then triturated with cold EtOAc) to give the desired product as a light brown gel (0.634 g, 92%). LCMS for C22H26ClN4O2 (M+H)+: m/z=413.0.
