実験手順

To a mixture of 2-chloro-5-(2-methyl-2-(tetrahydro-2H-pyran-2-yloxy)propyl)-6a,7,9,10-tetrahydro-[1,4]oxazino[3,4-h]pteridin-6(5H)-one (96.2 mg, 0.242 mmol) and iodomethane (0.076 ml, 1.21 mmol) in DMSO (4 ml) at 0° C. was added sodium 2-methylpropan-2-olate (46.6 mg, 0.485 mmol). The ice-bath was removed and the reaction mixture was stirred at room temperature for 16 h, followed by being poured into water. Extraction with EtOAc, washing with water, drying and concentration in vacuo gave crude 2-chloro-6a-methyl-5-(2-methyl-2-(tetrahydro-2H-pyran-2-yloxy)propyl)-6a,7,9,10-tetrahydro-[1,4]oxazino[3,4-h]pteridin-6(5H)-one (133 mg, 0.322 mmol) as a red oil which was used without further purification. MS [M+H] found 411.
