A solution of 4-(2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-2,3,4,5,6,7-hexahydro-1H-cyclopenta[d]pyrimidin-4-yl)benzonitrile (example 1, 70 mg, 0.18 mmol) in a mixture of tetrahydrofuran (1.5 mL) and N,N-dimethylformamide (150 μL) is treated with sodium hydride (60% in mineral oil, 28 mg, 0.7 mmol) and stirred at room temperature for 5 min Methyl 4-(chlorosulfonyl)butanoate (106 mg, 0.53 mmol) is added, and the mixture is stirred at 50° C. over night. The mixture is diluted with water and N,N-dimethylformamide and purified by reversed phase HPLC (Wate7rs SunFire™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 48 mg; ESI mass spectrum [M+H]+=562; Retention time HPLC: 0.95 min (Z018_S04).
