To a solution of 3-methylbenzenethiol (0.55 mL, 0.0046 mol) in DMF (10 mL, 0.2 mol) was added sodium hydride (0.093 g, 0.0023 mol). The mixture was stirred at room temperature for 10 minutes and then 6-{[(1R,3S,4S)-3-{[tert-butyl(dimethyl)silyl]oxy}-4-({[tert-butyl(dimethyl)silyl]oxy}methyl)cyclopentyl]oxy}-8-iodo-9-(tetrahydro-2H-pyran-2-yl)-9H-purine (400 mg, 0.0006 mol) (Example 115, steps a-b) was added and the solution was heated at 150° C. for 8 hours. The reaction was cooled, quenched by addition of water and the mixture was extracted with ethyl acetate, washed with water, brine, dried (Na2SO4), filtered and concentrated. The residue was purified by flash chromatography (0 to 30% ethyl acetate/hexanes) to obtain 296 mg (80%) of the title compound.
