To a solution of 5,6-diamino-3-(4-methoxybenzyl)-1-methylpyrimidine-2,4(1H,3H)-dione (100 mg, 0.362 mmol, Intermediate 59) in ethanol (3 mL) was added 3-(3-(trifluoromethoxy)phenoxy)propanoic acid (96 mg, 0.364 mmol) and EDCI (105 mg, 0.546 mmol). The reaction was stirred at room temperature for 3 h. Then the mixture was diluted with water and the precipitate was collected by filtration and rinsed with water. The solids were then dissolved in ethyl acetate. This organic solution was dried over sodium sulfate and concentrated to give 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, 79.3%) as a yellow solid. LCMS retention time 1.422 min; LCMS MH+ 523.
