Procedure

To a solution of N-[(3aS,4R,6R,6aR)-6-({[tert-butyl(dimethyl)silyl]oxy}methyl)-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl]-6-iodopyrimidin-4-amine (0.300 g, 0.594 mmol) in DMF (2.46 mL) was added CuI (0.0113 g, 0.0594 mmol) and bis(triphenylphosphine)palladium(II) chloride (0.0292 g, 0.0415 mmol). The tube was sealed and flushed with argon. Et3N (0.165 mL, 1.19 mol) was added and the reaction was stirred for 1 h. Phenylacetylene (0.216 mL, 1.96 mmol) was added and the reaction was stirred overnight. The suspension was filtered and the filtrate was concentrated in vacuo. The crude mixture was purified by flash chromatography (10 to 40% EtOAc/hexanes) to afford the title compound as a yellow oil (0.238 g, 84%). LC/MS: Rt=2.47 min, ES+ 480 (FA standard).
