Reaction Steps

Phenyl isocyanate (70 μL, 0.5 M in anhydrous DCM, 0.03 mmol, 1.1 equiv.) was added to a solution of TFA salt of 6-amino-4-{[4-chloro-3-(trifluoromethyl)benzyl]amino}quinazoline-8-carboxamide (16 mg, 0.03 mmol, 1.0 equiv.) and triethylamine (16 μL, 0.09 mmol, 3.0 equiv.) in anhydrous DCM (1 mL). The resulting mixture was stirred at 40° C. for 3 hrs. The title compound was obtained by pre-HPLC in 79% yield. Mass: M+H+: 515.
