Procedure
tert-butyl 3-morpholinoazetidine-1-carboxylate (31 mg) was treated with 4N HCl in dioxane (5 eq) in 1 mL of DCM. The reaction mixture was stirred for 3 hours at room temperature and then concentrated to dryness to yield 4-(azetidin-3-yl)morpholine in quantitative yield. 4-(6-(Bromomethyl)-2-chloropyrido[3,2-d]pyrimidin-4-yl)morpholine 7 (0.413 g) was reacted with 4-(azetidin-3-yl)morpholine via General Procedure B to afford 0.4 g 4-(1-((2-chloro-4-morpholinopyrido[3,2-d]pyrimidin-6-yl)methyl)azetidin-3-yl)morpholine
