Versuchsvorschrift

A mixture of 4-(amino(5-oxo-2-(3-(trifluoromethyl)phenylamino)cyclopent-1-enyl)-methyl)benzonitrile hydrochloride (intermediate 13, 11.8 g, 26.1 mmol based on 90% purity) in acetonitrile (100 mL) and 1,1′-carbonyldiimidazole (5.28 g, 32.6 mmol) is treated with triethylamine (0.9 mL, 6.5 mmol), and the mixture is stirred at room temperature for 1 h. All volatiles are removed under reduced pressure, and the residue is treated with water. The precipitate is filtered, washed with water and dried. The residue is purified by recrystallization from hot toluene (130 mL). Yield: 8.6 g; ESI mass spectrum [M+H]+=398; Retention time HPLC: 1.06 min (V011_S01). LH4BRM00213
