Procedure

A suspension of 3-[5-(2,6-Dioxo-1,3-dipropyl-2,3,6,7-tetrahydro-1H-purin-8-yl)-bicyclo-[3.2.1]oct-1-yl]-acrylic acid methyl ester (Example 12) (0.58 mmol, 0.25 g) and 10% Pd/C (50% H2O, 0.029 mmol, 0.062 g) in MeOH (20 ml) was hydrogenated at 40 psi overnight. The completed reaction was filtered through Celite, rinsing with MeOH. Evaporation provided the desired product (0.196 g, 79%) as an oil. MS (ES+) 431.18 (M+H)
