Procedimiento

(R)-2-(1-(8-cyclopentyl-7-ethyl-5-methyl-6-oxo-5,6,7,8-tetrahydropteridin-2-yl)-1H-imidazol-4-yl)acetonitrile (Example 35, 0.08 g, 0.218 mmol) and PtO2 (40 mg) were suspended in 2 mL of EtOAc and the resulting mixture was stirred under an atmosphere of hydrogen (1 atm, balloon) for 18 h. The resulting solution was filtered through Celite, concentrated, then purified by preparative HPLC to give the title compound (34 mg). LCMS: 370.1 m/z (M+H)+; ret. Time: 4.09 (Analytical Method C).
