Participants

Reaction Steps

The title compound was prepared following the procedure described in Example-1 using N4-(tert-butyl)quinazoline-4,8-diamine (Intermediate-55, 100 mg, 0.46 mmol), 2-chloro-4-fluoro-5-(pivalamidomethyl)benzoic acid (Intermediate-63, 159 mg, 0.56 mmol), oxalyl chloride (117 mg, 0.93 mmol), DMF (1 drop) and DIPEA (178 mg, 1.38 mmol) in CH2Cl2 (5 mL) to afford 20 mg of the title product. 1H NMR (300 MHz, DMSO-d6): δ 10.18 (s, 1H), 8.69-8.66 (d, J=7.2 Hz, 1H), 8.47 (s, 1H), 8.16-8.11 (m, 2H), 7.62-7.57 (m, 2H), 7.52-7.45 (m, 2H), 4.31-4.29 (d, J=5.7 Hz, 2H), 1.53 (s, 9H), 1.10 (s, 9H); MS [M+H]+: 486.45.
