To a solution of N-(6-amino-3-(4-methoxybenzyl)-1-methyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)-4-(3-(trifluoromethoxy)phenoxy)butanamide (150 mg, 0.287 mmol) in ethanol (7 mL) was added 2N NaOH (1 mL). The mixture was stirred at 80° C. for 3 h. The reaction was neutralized with saturated ammonium chloride and the product precipitated. The solids were collected and washed with water. The solids were dissolved in ethyl acetate, dried over sodium sulfate and concentrated to give 1-(4-methoxybenzyl)-3-methyl-8-(3-(3-(trifluoromethoxy)phenoxy)propyl)-1H-purine-2,6(3H,7H)-dione (130 mg, 89.7%) as a light yellow solid. LCMS retention time 1.635 min; LCMS MH+ 505.
