Procedure
The title compound was prepared following the procedure described in Example-1 using N4-(4,4-difluorocyclohexyl)quinazoline-4,8-diamine (Intermediate-9, 60 mg, 0.215 mmol), 2-chloro-5-(pivalamidomethyl)benzoic acid (Intermediate-5, 116 mg, 0.431 mmol), oxalyl chloride (81 mg, 0.65 mmol), DMF (1 drop) and DIPEA (84 mg, 0.65 mmol) in CH2Cl2 (3 mL) to afford 25 mg of the title product. 1H NMR (300 MHz, DMSO-d6): δ 10.13 (s, 1H), 8.71 (d, 1H), 8.49 (s, 1H), 8.19 (m, 2H), 8.05 (d, 1H), 7.57-7.54 (m, 3H), 7.41 (d, 1H), 4.41 (m, 1H), 4.31 (d, 2H), 2.00 (m, 6H), 1.75 (m, 2H), 1.12 (s, 9H); MS (m/z): 530.20 (M+H)+.
