2-Chloro-6-((R)-3-methyl-morpholin-4-yl)-9H-purine (712 mg, 2.81 mmol), diisopropylethylamine (0.98 mL, 5.61 mmol), and (S)-3-methylmorpholin hydrochloride (579 mg, 4.21 mmol) were stirred in 2-butanol (3 mL) in a closed 5 mL microwave tube under argon at 50° C., until all ingredients were dissolved. The reaction was then stirred at 175° C. for 48 hours. The organic layer was diluted with 200 mL of CH2Cl2 and washed with brine. Drying over Na2SO4, filtering and concentration under reduced pressure gave a residue, which was purified by column chromatography (40 g SiO2, CH2Cl2/EtOH/aq NH3 in a gradient from 100/0/0.1 to 90/10/0.1) to give the product as a solid (588 mg, 66%).
