Procedure
2,4-Dichloro-N-((tetrahydrofuran-3-yl)methyl)pyrimidin-5-amine (7 g, 28.2 mmol), morpholine-3-carboxylic acid hydrochloride (832 mg, 4.97 mmol), and DIPEA (2.67 ml, 15.28 mmol) were combined in DMSO (8 ml). The reaction mixture was heated overnight at 100° C. Upon cooling the solution was diluted with water then extracted twice with ethyl acetate. The organic layers were combined, dried over magnesium sulfate, filtered, and evaporated in vacuo to give 6.6 g of 2-chloro-5-((tetrahydrofuran-3-yl)methyl)-6a,7,9,10-tetrahydro-[1,4]oxazino[3,4-h]pteridin-6(5H)-one as a brown oil which was used without further purification. [M+H] found 325.
