Versuchsvorschrift

A mixture of 5-chloro-1,3-dimethyl-1H-pyrazole-4-carboxylic acid {4-[3-cyclopropylmethyl-1-(2-fluoro-benzyl)-2,6-dioxo-2,3,6,7-tetrahydro-1H-purin-8-ylmethyl]-phenyl}-methyl-amide (81.5 mg, 0.14 mmol) (prepared as described in example 104), 10% palladium on carbon (313 mg), and sodium acetate (28.3 mg, 0.35 mmol) in dichloromethane (25 mL) and methanol (25 mL) was hydrogenated at 50 psi on a Parr apparatus for 8 days. At this time, the reaction was filtered through a pad of celite and washed with a 90/10 dichloromethane/methanol solution (100 mL). The filtrated was concentrated in vacuo. The resulting residue was purified by HPLC (15–60% acetonitrile/water (0.075% trifluoroacetic acid in both solvents) over 40 min). Fractions with the desired product were combined and concentrated in vacuo. The resulting residue was diluted with dichloromethane (100 mL) and was washed with a saturated aqueous sodium bicarbonate solution (25 mL). The organics were dried over magnesium sulfate, filtered, and concentrated in vacuo. The resulting solid was dried in vacuo for 24 h to afford 1,3-dimethyl-1H-pyrazole-4-carboxylic acid {4-[3-cyclopropylmethyl-1-(2-fluoro-benzyl)-2,6-dioxo-2,3,6,7-tetrahydro-1H-purin-8-ylmethyl]-phenyl}-methyl-amide (7.0 mg, 9.1%) as a white solid: 1H NMR (DMSO-d6, 300 MHz) δ13.122 (broad s, 1H), 6.79 (m, 9H), 6.33 (s, 1H), 4.76 (s, 2H), 3.70 (s, 2H), 3.47 (d, J=6.96 Hz, 2H), 3.11 (s, 3H), 2.87 (s, 3H), 1.75 (s, 3H), 0.85 (broad s, 1H), 0.026 (m, 4H).
