Procedure

A solution of 1.0 g of (Nα-FMOC-Nε-CBZ-lysyl)guanosine in 150 mL of DMF was hydrogenated for 3.5 hr at 48 psi in the presence of 0.7 g of 10% Pd/C. The mixture was filtered and the filtrate evaporated and then treated with 30 mL of EtOH followed by 20 mL of H2O. The resulting solid was recrystallized from MeOH-EtOAc.
