Reaction Steps

9-((1R,2S,3R,4S)-2,3-Dihydroxy-4-propionylamino-cyclopentyl)-6-(2,2-diphenyl-ethylamino)-9H-purine-2-carboxylic acid (2-amino-ethyl)-amide (25 mg, 0.044 mmol) is dissolved in toluene (2 ml) and iPrOH (1 ml). N-[1-(2-Pyridinyl)-4-piperidinyl]-1H-imidazole-1-carboxamide (prepared using the procedure described in international patent application WO 01/94368) (12 mg, 0.044 mmol) is added as a solution in dichloromethane. The reaction mixture is stirred at room temperature. The reaction is shown to be complete by LCMS after 24 hours. The solvent is removed in vacuo. The title compound is obtained by flash column chromatography (Isolute™ C18, 0-100% acetonitrile in water). MS (ES+) m/e 388.7(MH+).
