To a solution of 8-bromo-7-(4-chlorobenzyl)-3-methyl-1H-purine-2,6(3H,7H)-dione (0.2 g, 0.54 mmol, intermediate 8) in DMF (5 mL) was added 2-chloro-N,N-dimethylethanamine (0.87 mg, 0.83 mmol), potassium carbonate (0.15 g, 1.08 mmol), and TBAI (2 mg, 0.02 mmol). The reaction was heated at 80° C. overnight. The mixture was cooled and partitioned between ethyl acetate and water. The combined organic layer was dried over sodium sulfate, filtered and concentrated to give a crude product (0.2 g, 84%) as yellow oil, which was used without purification. LCMS MH+ 442.
