Reaction Steps

To a solution of 1-(4-methoxybenzyl)-3-methyl-8-(3-(3-(trifluoromethoxy)phenoxy)propyl)-1H-purine-2,6(3H,7H)-dione (130 mg, 0.261 mmol, intermediate 60) in DMF (3 mL) was added 1-(bromomethyl)-4-chlorobenzene (70 mg, 0.345 mmol), followed by potassium carbonate (107 mg, 0.775 mmol) and TBAI (5 mg, 0.014 mmol). The mixture was stirred at 60° C. overnight. The reaction was cooled and partitioned between ethyl acetate and water. The combined organic phase was washed with brine, dried over sodium sulfate, and concentrated to give the crude product 7-(4-chlorobenzyl)-1-(4-methoxybenzyl)-3-methyl-8-(3-(3-(trifluoromethoxy)phenoxy)propyl)-1H-purine-2,6(3H,7H)-dione (150 mg, 92.5% yield) as a yellow oil. LCMS retention time 2.075 min; LCMS MH+ 629.
