Reaction Steps

The title compound is prepared using a method that is analogous to that used to prepare the compound of Example 22 using N-{(1S,2R,3S,4R)-4-[2-chloro-6-(2,2-diphenyl-ethylamino)-purin-9-yl]-2,3-dihydroxy-cyclopentyl}-3-phenyl-propionamide, (R)-pyrrolidin-3-ylamine (34 mg, 0.4 mmol) and sodium iodide (6 mg, 0.04 mmol) to give a mixture of two regioisomers which are purified by reverse phase column chromatography (Isolute™ C18, 0-100% acetonitrile in water—0.1% TFA) to give a product which is predominantly N-{(1S,2R,3S,4R)-4-[2-((R)-3-Amino-pyrrolidin-1-yl)-6-(2,2-diphenyl-ethylamino)-purin-9-yl]-2,3-dihydroxy-cyclopentyl}-2-phenyl-acetamide.
