To a solution of N-(6-amino-3-(4-methoxybenzyl)-1-methyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)-2-(3-(trifluoromethoxy)phenyl)acetamide (70 mg, 0.146 mmol) in ethanol (7 ml) was added 2N sodium hydroxide (1 ml). The reaction was stirred at 80° C. for 3 h. The reaction was neutralized with aqueous ammonium chloride, filtered and the solids were rinsed with water. The solid residue was dissolved in ethyl acetate, dried over sodium sulfate, filtered and concentrated to give 1-(4-methoxybenzyl)-3-methyl-8-(3-(trifluoromethoxy)benzyl)-1H-purine-2,6(3H,7H)-dione (60 mg, 89.1%) as light yellow solid. LCMS retention time 1.499 min; LCMS MH+ 461.
