Reaction Steps

To a solution of 8-chloro-7-(4-chlorobenzyl)-1-methyl-1H-purine-2,6(3H,7H)-dione (50 mg, 0.154 mmol, intermediate 10) in DMF (3 mL) was added (bromomethyl)benzene (50 mg, 0.29 mmol) followed by potassium carbonate (40 mg, 0.29 mmol). The mixture was stirred at 40° C. overnight. The mixture was diluted with ethyl acetate and water, and the phases were separated. The organic phase was washed with brine, dried over sodium sulfate, filtered and concentrated. The crude product was purified by silica gel chromatography eluting with petroleum/ethyl acetate (5:1 to 3:1) to give 3-benzyl-8-chloro-7-(4-chlorobenzyl)-1-methyl-1H-purine-2,6(3H,7H)-dione (60 mg, 93.6% yield) as white solid. LCMS retention time 1.893 min; LCMS MH+ 415.
