Procedure
To a solution of 3-benzyl-8-chloro-7-(4-chlorobenzyl)-1-methyl-1H-purine-2,6(3H,7H)-dione (60 mg, 0.145 mmol) in DMF (3 mL) was added 3-(trifluoromethyl)phenol (35 mg, 0.215 mmol) followed by potassium carbonate (40 mg, 0.29 mmol). The mixture was stirred at 100° C. for 2 h. 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 give crude product was purified by preparative HPLC to give 3-benzyl-7-(4-chlorobenzyl)-1-methyl-8-(3-(trifluoromethyl)phenoxy)-1H-purine-2,6(3H,7H)-dione (31 mg, 41.7% yield) as white solid. 1H-NMR (CDCl3) δ 7.65(s, 1H), 7.58-7.57(m, 2H), 7.45-7.41(m, 5H), 7.33-7.27(m, 5H), 5.42(s, 2H), 5.09(s, 2H), 3.41(s, 3H). LCMS retention time 3.649 min; LCMS (M+H) 541.
