Reaction Conditions

Reaction Steps

To a 1-L 3-necked round bottomed flask equipped with a mechanical stirrer and a thermometer, was charged 2-amino-6-benzyloxypurine (24 g, 0.1 moles), lithium hydride (0.48 g, 0.06 moles) and DMF (40 mL). The mixture was heated at 60° C. for about 1 hour under an atmosphere of argon. 77 (60 g, 0.1 moles) in 20 mL DMF was added. The reaction temperature was heated at 105° C. for 5 hours, cooled to room temperature and diluted with EtOAc (600 mL). The organic layer was washed with brine (300 mL), 1 M citric acid (150 mL), and NaHCO3 solution (100 mL). The organic layer was concentrated in vacuo to furnish crude title product (60 g) as an oil. It was crystallized from EtOAc and hexane to give 23 g of the title compound as a crystalline solid.
