Versuchsvorschrift

To a solution of N-{3-[5-(1H-pyrazol-4-yl)-1H-benzimidazol-1-yl]phenyl}-N′-(2,2,2-trifluoroethyl)urea HCl salt (20.0 mg, 0.0458 mmol) in acetonitrile (1 mL) was added (2E)-4,4,4-trifluorobut-2-enenitrile (8.3 mg, 0.069 mmol) and 1,8-diazabicyclo[5.4.0]undec-7-ene (14 μL, 0.092 mmol). The solution was stirred and heated at 80° C. for several hours. The reaction solution was concentrated under reduced pressure to dryness. The residue was dissolved in MeOH, and purified by RP-HPLC (pH=10) to afford the desired compound. LCMS (M+H)+: m/z=522.1.
