Procedure

Carbonic acid (1S,4R)-4-(6-{[bis-(4-methoxy-phenyl)-methyl]-amino}-2-chloro-purin-9-yl)-cyclopent-2-enyl ester ethyl ester (2.00 g, 3.64 mmol), di-t-butyl iminodicarboxylate (0.87 g, 4.00 mmol) and triphenylphosphine (0.14 g, 0.55 mmol) are placed in an oven-dried flask under an atmosphere of argon. Dry deoxygenated THF (20 ml) is added followed by tetrakis(triphenylphosphine)palladium(0) (0.21 g, 0.18 mmol) and the mixture is stirred at room temperature. The reaction is shown to be complete by LCMS after 3 hours. The solvent is removed in vacuo and the title compound is obtained after purification by flash column chromatography (silica, iso-hexane/ethyl acetate 4:1). 1H nmr (CDCl3, 400 MHz); 8.20(s, 1H), 7.25(d, 4H), 6.85(d, 4H), 6.60(m, 1H), 6.35(m, 1H), 6.10(m, 1H), 5.80(m, 1H), 5.65(m, 1H), 5.35(m, 1H), 3.80(s, 6H), 3.15(m, 1H), 2.10(m, 1H), 1.55(s, 18H).
