反応手順
A solution of 4-chloro-8-nitroquinazoline (Intermediate-7, step-2, 150 mg, 0.72 mmol) and 2-fluoro-5-(trifluoromethyl)aniline (387 mg, 2.16 mmol) in THF (4 mL) was heated at 50° C. for 2 h. Then water was added to the reaction mixture and it 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 250 mg of the title product. 1H NMR (300 MHz, DMSO d6): δ 10.46 (s, 1H), 8.74-8.71 (d, J=8.7 Hz, 1H), 8.63 (s, 1H), 8.43-8.40 (d, J=7.2 Hz, 1H), 8.01 (d, 1H), 7.86-7.81 (m, 2H), 7.66-7.63 (t, J=9.3 Hz, 1H); MS [M+H]+: 353.14.
