Reaction Steps

To a solution of 3-(2-bromoethyl)-7-(4-chlorobenzyl)-1-methyl-8-(3-(trifluoromethoxy)phenoxy)-1H-purine-2,6(3H,7H)-dione (110 mg, 0.192 mmol) in DMF (3 mL) was added dimethylamine hydrochloride (150 mg, 1.84 mmol), followed by potassium carbonate (100 mg, 0.725 mmol). The mixture was stirred at 40° C. for 16 h; then it was diluted with ethyl acetate and water. The phases were separated and the organic phase was washed with brine, dried over sodium sulfate, filtered and concentrated. The residue was purified by preparative HPLC to give 7-(4-chlorobenzyl)-3-(2-(dimethylamino)ethyl)-1-methyl-8-(3-(trifluoromethoxy)phenoxy)-1H-purine-2,6(3H,7H)-dione (15 mg, 13.3% yield) as white solid.
