Reaction Steps

To a solution of 1-(4-methoxybenzyl)-3-methyl-8-(3-(trifluoromethoxy)benzyl)-1H-purine-2,6(3H,7H)-dione (136 mg, 0.295 mmol) in DMF (2 mL) was added 2-(bromomethyl)pyridine hydrobromide (112 mg, 0.442 mmol) followed by potassium carbonate (102 mg, 0.738 mmol). The reaction was stirred at 65° C. for 2 h. The mixture partitioned between ethyl acetate and brine. The organic layer was dried and concentrated to give a crude product, which was purified by silica gel chromatography eluting with DCM/methanol (45:1) to give 1-(4-methoxybenzyl)-3-methyl-7-(pyridin-2-ylmethyl)-8-(3-(trifluoromethoxy)benzyl)-1H-purine-2,6(3H,7H)-dione (96 mg, 59% yield) as a white solid. LCMS retention time 1.791 min; LCMS MH+ 552.
