Reaction Conditions

Reaction Steps

2,6-Dichloro-9H-purine (2.36 g, 12.5 mmol), (R)-3-methylmorpholin hydrochloride (1.89 g, 13.8 mmol), and diisopropylethylamine (5.46 mL, 31.3 mmol) were dissolved in 15 mL of isopropanol, and the reaction mixture was stirred for 18 hours at 75° C. The reaction mixture was then diluted with 200 mL of CH2Cl2. The organic solvents were washed with aqueous Na2CO3, followed by water and brine. Drying over Na2SO4, filtering and concentration under reduced pressure gave a residue, which was purified by column chromatography (150 g SiO2, CH2Cl2/EtOH/aq NH3 in a ratio of 96/4/0.1) to give the product as a solid (2.87 g, 91%).
