Dimethylformamide → 2-Chloro-5-(pivalamidomethyl)-N-(8-((3-(trifluoromethyl)phenyl)amino)quinolin-4-yl)benzamide

To a solution of N-(3-(trifluoromethyl)phenyl)quinoline-4,8-diamine (Intermediate-12, 80 mg, 0.264 mmol) in DMF (2 mL) was added NaH (26 mg, 0.65 mmol, 60% in mineral oil) at 0° C. and the reaction mixture was stirred at 0-5° C. for 30 minutes. Then a solution of 4-nitrophenyl 2-chloro-5-(pivalamidomethyl)benzoate (Intermediate-13, 123 mg, 0.314 mmol) in DMF (1 mL) was added to the reaction mixture at 0° C. and the reaction mixture was stirred at 0° C.—rt for 2 h. Then the reaction mixture was quenched with water and was extracted with EtOAc. The organic layer was washed with brine, separated, dried, filtered and concentrated. The residue was purified by column chromatography to afford 15 mg of the title product. 1H NMR (300 MHz, DMSO-d6): δ 10.92 (s, 1H), 9.07 (s, 1H), 8.86 (d, J=4.8 Hz, 1H), 8.21-8.18 (m, 2H), 7.80-7.57 (m, 3H), 7.59-7.54 (m, 5H), 7.39 (d, J=8.4 Hz, 1H), 7.25 (d, J=7.2 Hz, 1H), 4.32 (d, J=6.0 Hz, 2H), 1.19 (s, 9H); MS [M+H]+: 555.25.
