tert-butyl 4-((2-chloro-4-morpholinopyrido[3,2-d]pyrimidin-6-yl)methyl)piperidine-1-carboxylate from Example 137 (0.33 g) in DCM (5 mL) was treated with 4N HCl in dioxane (0.9 mL) for 30 minutes at room temperature. The reaction mixture was concentrated to dryness to afford quantitative yield of 4-(2-chloro-6-(piperidin-4-ylmethyl)pyrido[3,2-d]pyrimidin-4-yl)morpholine.
