Procedure

Methyl 6-[(2,2-diphenylethyl)amino]-9-{(2R,3R,4S,5S)-5-[(ethylamino) carbonyl]-3,4-dihydroxytetra-hydro-2-furanyl}-9H-purine-2-carboxylate (Preparation 11) (100 mg, 0.18 mmol) and 2-(4-isopropyl-1-piperidinyl)ethylamine (Preparation 17) (300 mg, 1.76 mmol) were heated at 120° C. under a nitrogen atmosphere for three hours. The reaction mixture was allowed to cool to room temperature and purified by column chromatography on silica gel eluting with dichloromethane:methanol:concentrated aqueous ammonia (90:10:1 by volume) to afford the title compound as a white solid (76 mg, 62%).
