A suspension of N-(3-bromopropyl)-2,6-dichloropyrimidin-4-amine (47 g, 165 mmol) and potassium carbonate (68.4 g, 495 mmol) in 1,4-dioxane (100 mL) and water (100 mL), was heated to 60° C. overnight. The mixture was evaporated to remove the dioxane solvent and the mixture was adjusted to pH ˜6 with HCl (6M). The mixture was extracted with ethyl acetate to remove by product and aqueous phase was adjusted to pH ˜7 with NaOH (2M), evaporated to afford the title compound (17 g, 55% yield).
