To a solution of 3-methyl-1-(2-(2-(tetrahydro-2H-pyran-2-yloxy)ethoxy)ethyl)-8-(3-(trifluoromethoxy)phenoxy)-7-((2-(trimethylsilyl)ethoxy)methyl)-1H-purine-2,6(3H,7H)-dione (0.64 g, 1.16 mmol,) in ethanol (15 mL) was added HCl (3 mL); then it was refluxed overnight. The solvent was concentrated to give a crude product which was purified by a column chromatography to give 1-(2-(2-hydroxyethoxy)ethyl)-3-methyl-8-(3-(trifluoromethoxy)phenoxy)-1H-purine-2,6(3H,7H)-dione (420 mg, 84% yield) as a white solid. LCMS retention time 1.209 min, LCMS MH+ 431.
