Bromoethane (20 μL, 0.27 mmol) is added to a solution of 4-(2,5-dioxo-1-(3-(trifluoro-methyl)phenyl)-2,3,4,5,6,7-hexahydro-1H-cyclopenta[d]pyrimidin-4-yl)-3-(methyl-sulfonyl)benzonitrile (example 10, 60 mg, 0.11 mmol based on 90% purity) and cesium carbonate (74 mg, 0.23 mmol) in N,N-dimethylformamide (2.0 mL). The mixture is stirred at room temperature over night and purified by reversed phase HPLC (Waters SunFire™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 23 mg; ESI mass spectrum [M+H]+=504; Retention time HPLC: 0.86 min (005_CA01).
