Reaction Steps

N-{(1S,2R,3S,4R)-4-[2-Chloro-6-(2,2-diphenyl-ethylamino)-purin-9-yl]-2,3-dihydroxy-cyclopentyl}-propionamide (46.8 mg, 90 μmol) of Example 4, L-phenylalaninol (271 mg, 1.80 mmol) and sodium iodide (6.75 mg, 45 μmol) are placed in a 0.5-2.5 ml microwave vial. Acetonitrile (0.25 ml) and NMP (0.25 ml) are added and the reaction mixture is heated using microwave radiation in a Personal Chemistry Emrys™ Optimizer microwave reactor at 200° C. The reaction is shown to be complete by LCMS after 1 hour. The title compound is obtained after purification by reverse phase column chromatography (Isolute™ C18, 0-100% acetonitrile in water—0.1% TFA). MS (ES+) m/e 636 (MH+).
