Reaction Steps

To a solution of 8-bromo-1-(3-hydroxybutyl)-3-methyl-7-((2-(trimethylsilyl)ethoxy)methyl)-1H-purine-2,6(3H,7H)-dione (1 g, 2.2 mmol) in DNF (10 mL) was added 3-(trifluoromethoxy)phenol (0.6 g, 3 mmol) followed by potassium carbonate (0.6 g, 4.4 mmol). The reaction was stirred at 80° C. for 4 h. The mixture was diluted with ethyl acetate and washed with brine. The organic phase was dried and concentrated to give 1-(3-hydroxybutyl)-3-methyl-8-(3-(trifluoromethoxy)phenoxy)-7-((2-(trimethylsilyl)ethoxy)methyl)-1H-purine-2,6(3H,7H)-dione (1.1 g, 91.8% yield) as yellow syrup. LCMS retention time 2.036 min; LCMS MH+ 545.
