Procedure
A solution of 2-(4-(3-amino-6-Chloroquinolin-4-ylamino)phenyl)-2-methylpropanenitrile (Compound of Preparation G, 3.3 g, 9.8214 mmol) and triethylamine (1.34 g, 12.74 mmol) in CH2Cl2 (120 mL) was added over 40 min to a solution of triphosgene (3.5 g, 11.7852 mmol) in 80 mL of CH2Cl2 at 0° C. with an ice-bath. The reaction mixture was stirred for 20 min at this temperature then quenched with saturated aqueous NaHCO3, stirred for 5 min and extracted with CH2Cl2. The organic layer was dried over Na2SO4, filtered and evaporated in vacuo to obtain the title compound. Yield: 1.2 g (34%); 1H NMR (DMSO-d6, 300 MHz): δ 12.190 (s, 1H), 8.921 (s, 1H), 8.069-8.100 (d, 1H, J=8.7 Hz), 7.807-7.835 (d, 2H, J=8.4 Hz), 7.641-7.694 (m, 3H), 6.808-6.815 (d, 1H, J=2.1 Hz), 1.766 (s, 6H); MS: m/z 363 (M+).
