4-{Amino-[6-oxo-2-(3-trifluoromethyl-phenylamino)-cyclohex-1-enyl]-methyl}-3-bromo-benzonitrile (INTERMEDIATE 21, 16.5 g, 33 mmol) is suspended in acetonitrile (150 mL) and triethylamine (3.47 mL, 24.7 mmol) and 1,1′-carbonyldiimidazole (6.7 g, 41.2 mmol) are added. The mixture is stirred at room temperature for 1 h. The solvent is evaporated under reduced pressure and water is added. The product precipitates; the precipitate is filtered off, washed with water and dried. Yield: 14 g. ESI mass spectrum: [M+H]+=490 (bromine isotope pattern); Retention time HPLC: 0.64 min (X012_S02).
