Reaction Conditions

Reaction Steps

To a solution of 2-(3-(trifluoromethoxy)phenoxy)ethanol (0.64 g, 2.9 mmol, intermediate 5) in THF (15 mL) was added sodium hydride (0.23 g, 9.67 mmol) at 0° C. it was stirred at 0° C. for 30 min, then 8-bromo-3-methyl-1-(3-(tetrahydro-2H-pyran-2-yloxy)propyl)-7-((2-(trimethylsilyl)ethoxy)methyl)-1H-purine-2,6(3H,7H)-dione (1.0 g, 1.93 mmol, intermediate 16 step 1) was added. The mixture was stirred 16 h. The reaction was quenched with aq. ammonium chloride (2 mL) at 0° C.; then it was partitioned between ethyl acetate and water. The organic phases were combined, dried over sodium sulfate, filtered and concentrated to give a crude product which was used without purification. LCMS retention time 2.144; LCMS MH+-THP 575.
