Participants

Reaction Steps

To a solution of 5,6-diamino-3-(4-methoxybenzyl)-1-methylpyrimidine-2,4(1H,3H)-dione (50 mg, 0.181 mmol, intermediate 59) in ethanol (3 ml) was added 2-(3-(trifluoromethoxy)phenyl)acetic acid (40 mg, 0.181 mmol) and EDCI (52 mg, 0.271 mmol) The mixture was stirred at room temperature for 2 h. The reaction was diluted with water, 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 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, 80.1%) as light gray solid. LCMS retention time 1.239 min; LCMS MH+ 479.
