Under an atmosphere of argon, a mixture of 4-(4-bromo-2-(methylsulfonyl)phenyl)-1-(3-(trifluoromethyl)phenyl)-3,4,6,7-tetrahydro-1H-cyclopenta[d]pyrimidine-2,5-dione (intermediate 8, 110 mg, 0.21 mmol), zinc cyanide (32 mg, 0.27 mmol) and tetrakis (triphenylphosphine)palladium(0) (24 mg, 21 μmol) in N,N-dimethylformamide (2 mL) is heated at 110° C. over night and then cooled to room temperature. Water is added and the mixture is filtered. The precipitate is purified by flash chromatography on silica (gradient cyclohexane/ethyl acetate 8:2 to 3:7). Yield: 40 mg; ESI mass spectrum: [M+H]+=476; Retention time HPLC: 0.94 min (Z017_S04).
