Procedure

4-[4-(tert-Butoxycarbonyl)piperazin-1-yl]-7-chloroquinol-2-one (150 mg, 0.4 mmol), sodium hydride (15 mg, 0.6 mmol), N-phenyl(trifluoromethylsulfon)imide (208 mg, 0.56 mmol), and 2-methoxyethylamine (362 μL, 4.0 mmol) are treated according to method E yielding 85 mg of 4-[4-(tert-butoxycarbonyl)piperazin-1-yl]-7-chloro-2-(2-methoxyethylamino)quinoline. 74 mg thereof are treated with TFA-CH2Cl2 1:1 (0.6 mL) for 1 h and concentrated. The residue is converted into the title product with 4-fluorophenyl isocyanate (30 μL) and triethylamine (230 μL).
