To a solution of 2,5-dichloro-N-[3-(3-methoxyphenyl)propyl]pyrimidin-4-amine (0.50 g, 1.6 mmol) (prepared according to Example 10, Step A) and 2-(3-aminophenyl)ethanol (0.30 g, 2.2 mmol) (prepared according to Example 2, Step A) in 1,4-dioxane (13.6 mL) was added p-toluenesulfonic acid monohydrate (0.11 g, 0.58 mmol). The mixture was heated at 100° C. for 16 hours and the reaction was complete. After cooling, the mixture was filtered under vacuum. The cake was washed with cold EtOAc and H2O successively to give the desired product as a light brown gum (0.61 g, 92%). LCMS for C22H26ClN4O2 (M+H)+: m/z=413.1.
