Reaction Steps

The title compound was prepared following the procedure described in Example-1 using 4-ethoxyquinolin-8-amine (Intermediate-56, 80 mg, 0.425 mmol), 6-chloro-2-fluoro-3-(pivalamidomethyl)benzoic acid (Intermediate-2, 159 mg, 0.553 mmol), oxalyl chloride (162 mg, 1.27 mmol), DMF (1 drop) and DIPEA (219 mg, 1.7 mmol) in CH2Cl2 (2 mL) to afford 46 mg of the title product. 1H NMR (400 MHz, DMSO-d6): δ 10.59 (s, 1H), 8.71-8.68 (m, 2H), 8.13 (t, 1H), 7.93-7.90 (dd, J=1.2, 8.4 Hz, 1H), 7.61-7.57 (t, J=8.0 Hz, 1H), 7.42-7.40 (d, J=8.4 Hz, 1H), 7.36-7.23 (t, J=8.0 Hz, 1H), 7.12-7.11 (d, J=5.2 Hz, 1H), 4.35-4.29 (m, 4H), 1.50-1.47 (t, J=7.2 Hz, 3H), 1.14 (s, 9H); MS (m/z): 458.24 (M+H)+.
