To a stirred solution of N-[2-(2-amino-benzoyl)-5-chloro-pyridin-3-yl]-4-chloro-3-trifluoromethyl-benzenesulfonamide (48 mg, 0.097 mmol) in anhydrous THF (2 mL) and AcOH (400 μL) was added TMSisocyanate (32 μL, 0.22 mmol) and the resulting mixture was heated at 65° C. overnight. The crude reaction mixture was directly purified by HPLC to provide 4-Chloro-N-[5-chloro-2-(2-oxo-1,2-dihydro-quinazolin-4-yl)-pyridin-3-yl]-3-trifluoromethyl-benzenesulfonamide.
