Reaction Steps

Triethylamine (0.38 mL, 2.70 mmol) is added to a mixture of 4-(amino(5-oxo-2-(3-(tri-fluoromethyl)phenylamino)cyclopent-1-enyl)methyl)-3-chlorobenzonitrile hydrochloride (intermediate 20.1, 660 mg, 1.34 mmol based on 90% purity) and 1,1′-carbonyldiimidazole (270 mg, 1.68 mmol) in acetonitrile (5 mL), and the mixture is stirred at room temperature over night. Water and dichloromethane are added, and the phases are separated. The organic layer is concentrated under reduced pressure and purified by reversed phase HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 290 mg. ESI mass spectrum: [M+H]+=432; Retention time HPLC: 0.61 min (X012_S01).
