Reaction Steps

3-butyl-1-ethyl-7-(phenylmethyl)-3,7-dihydro-1H-purine-2,6-dione (0.353 g, 1.08 mmol) was dissolved in acetic acid (30 mL), 20% palladium hydroxide on carbon (0.238 g) was added, and the mixture was shaken under hydrogen (at 50 psi) overnight. The catalyst was removed by filtration through Celite® and washed with acetic acid. The filtrate was concentrated under reduced pressure to yield the title compound (0.227 g, 89%); 1H NMR (400 MHz; CDCl3) δ: 0.97 (3H, t), 1.28 (3H, t), 1.38-1.47 (2H, m), 1.74-1.82 (2H, m), 4.12-4.17 (4H, m), 7.80 (1H, s); m/z 237[MH+].
