(1R,2S,3R,5S)-3-[2-(4-Amino-cyclohexylamino)-6-(2,2-diphenyl-ethylamino)-purin-9-yl]-5-(4-methyl-pyrazol-1-yl)-cyclopentane-1,2-diol trifluoroacetate (Example 1) (0.020 g, 0.028 mmol) is dissolved in DCM (2 ml). Toluene (2 ml) and iPrOH (1 ml) are added followed by N-[1-(2-pyridinyl)-4-piperidinyl]-1H-imidazole-1-carboxamide (which is prepared using the method described in international patent application WO 01/94368) (0.03 mmol of a 0.1 M solution in DCM). The dichloromethane is removed by vacuo and the reaction mixture is stirred at room temperature. The reaction is shown to be complete by LCMS after 48 hours. The solvent is removed in vacuo. The title compound is obtained by flash column chromatography (Isolute™ C18, 0-100% acetonitrile in water—0.1% TFA). MS (ES+) m/e 811.5 (MH+).
