Reaction Steps

To a solution of 1-(3-hydroxybutyl)-3-methyl-8-(3-(trifluoromethoxy)phenoxy)-7-((2-(trimethylsilyl)ethoxy)methyl)-1H-purine-2,6(3H,7H)-dione (1.1 g, 2.02 mmol) in THF (5 mL) was added TBAF (5 mL, 1 mmol/L in THF) and the mixture was heated at reflux for 16 h. The mixture was cooled and diluted with ethyl acetate. The organic phase was washed with brine and saturated aqueous ammonium chloride; then it was dried and concentrated to give a crude product which was purified by silica gel chromatography eluting with DCM/methanol (45:1) to give (701 mg, 83.8% yield) as white solid. LCMS retention time 1.372 min; LCMS MH+ 415.
