Sodium hydride → 4-(3-(Cyanomethyl)-2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-2,3,4,5,6,7-hexahydro-1H-cyclopenta[d]pyrimidin-4-yl)benzonitrile

Participants

Reaction Steps

Sodium hydride (60% in mineral oil, 11 mg, 0.29 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)benzonitrile (example 1, 40 mg, 96 μmol) in acetonitrile (3.0 mL). After 20 min, 2-iodoacetonitrile (7 μL, 0.1 mmol) is added. The mixture is stirred at room temperature over night and purified by reversed phase HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 11 mg; ESI mass spectrum [M+H]+=437; Retention time HPLC: 0.63 min (X012_S01).
