Procedure

To a mixture of 3-pentyl-6-thioxo-8-(trifluoromethyl)-1,3,6,7-tetrahydro-2H-purin-2-one (0.15 g, 0.49 mmol) in a solution of sodium hydroxide in water (2 M, 2 mL) was added dimethyl sulfate (0.056 mL, 0.59 mmol). The reaction mixture was heated at 80° C. for 1.5 h, quenched with acetic acid and extracted with methylene chloride. The organic layer was dried (MgSO4), concentrate and purified by silica gel chromatography (0-20% EtOAc in hexane) to provide the product as a yellow solid (0.15 g, 95% yield). LCMS calculated for C12H16F3N4OS (M+H): 321.1. found: 321.1.
