Procedure

2,2-Bis(4-chlorophenyl)ethanamine (426 mg, 1.51 mmol) (J. Am. Chem. Soc., 1983, 105(10), 3138) was added to a stirred solution of (2R,3R,4S,5S)-4-(benzoyloxy)-2-(6-chloro-2-iodo-9H-purin-9-yl)-5-[(ethylamino)carbonyl]tetrahydro-3-furanyl benzoate (500 mg, 0.755 mmol) (Preparation 47) in isopropyl alcohol (20 ml) at room temperature. The reaction mixture was stirred at room temperature for 48 hours. The solvent was removed under reduced pressure to give a residue that was purified by column chromatography on silica gel eluting with dichloromethane:methanol:(99:1 by volume). The solvent was removed under reduced pressure to give the title compound (329 mg) as a foam.
