Reaction Steps

A mixture comprising 1-{(R)-1-[9-((1R,2S,3R,4S)-4-amino-2,3-dihydroxy-cyclopentyl)-6-(2,2-diphenyl-ethylamino)-9H-purin-2-yl]-pyrrolidin-3-yl}-3-pyridin-3-yl-urea (Example 26 step 2) (0.1 g, 0.16 mmol) and TEA (24 μA, 0.18 mmol) in THF (7 ml) at room temperature is treated with (S)-(−)-2-acetoxy-propionyl chloride (24 mg, 0.16 mmol) in MeCN (1 ml) at (0° C.) over 1 minute. The mixture is allowed to stir at room temperature for 18 h and then treated with sat. Na2CO3 (1 ml) and MeOH (1 ml) and then stirred for a further 2 days. The solvent is removed in vacuo and purification by reverse phase column chromatography (Isolute™ C18, 0-100% acetonitrile in water −0.3% NH3) affords the title compound as a white solid.
