Procedure

3-[4-(2,6-Dioxo-3-propyl-2,3,6,7-tetrahydro-1H-purin-8-yl)-bicyclo[2.2.2]oct-1-yl]-acrylic acid methyl ester (300 mg) was dissolved in 20 mL of THF. 10%Pd on C (25 mg) was added and the resulting reaction mixture was hydrogenated under 50 psi of H2 at rt for 6 h. The reaction mixture was filtered through Celite and the filtrate was concentrated under reduced pressure to afford 280 mg of the desired product.
