Reaction Steps
3-[4-(2,6-Dioxo-1,3-dipropyl-2,3,6,7-tetrahydro-1H-purin-8-yl)-bicyclo[2.2.2]oct-1-yl]-acrylic acid (Example 17) (0.050 g) was dissolved in 5 ml of MeOH and combined with 0.005 g of 10% Pd/C. The reaction vessel was purged three times with N2 and then placed under a balloon of H2 gas. After 2 h, the reaction mixture was filtered and conc'd to give 0.037 g (74% yield) of a white solid. (MH+=417.30)
