Procedure

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, 60 mg, 0.11 mmol) in acetonitrile (1.5 mL) is treated with dimethylamine (2.0 M in tetrahydrofuran, 270 μL, 0.53 mmol) and the mixture is stirred at room temperature for 30 min Water and N,N-dimethylformamide are added and the mixture is purified by reversed phase HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% NH3). Yield 28 mg, ESI mass spectrum [M+H]+=469; Retention time HPLC: 0.87 min (Z018_S04).
