実験手順
A solution of 4-nitrophenyl 4-(4-cyanophenyl)-2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-4,5,6,7-tetrahydro-1H-cyclopenta[d]pyrimidine-3(2H)-carboxylate (intermediate 4, 25 mg, 45 μmol) in acetonitrile (1.0 mL) is treated with ammonium carbonate (9 mg, 90 μmol), and the mixture is stirred at room temperature for 30 min and purified by reversed phase HPLC (Waters SunFire™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 3 mg; ESI mass spectrum [M+H]+=441; Retention time HPLC: 0.65 min (X018_S01).
