Versuchsvorschrift

To a suspension of {(1S,2R,3S,4R)-4-[2-(2-amino-ethylcarbamoyl)-6-(2,2-diphenyl-ethylamino)-purin-9-yl]-2,3-dihydroxy-cyclopentyl}-carbamic acid tert-butyl ester (2.5 g, 4.05 mmol) in IPA (10 ml) is added imidazole-1-carboxylic acid (3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl)-amide (Intermediate C) (151 ml of a 10 mg/ml solution in DCM, 5.56 mmol) and the reaction mixture is stirred at room temperature overnight. The solvent is removed in vacuo and the crude product is purified by chromatography on silica eluting with DCM/MeOH (25:1 increasing to 15:1). The resulting solid is further purified by dissolving in DCM and washing the solution with water, drying (MgSO4) and concentrating in vacuo to afford the title product. (MH+ 820.7)
