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-(difluoromethyl)-5-(isobutyramidomethyl)nicotinic acid (Intermediate-66, 150 mg, 0.55 mmol), oxalyl chloride (104 mg, 0.83 mmol), DMF (1 drop) and DIPEA (178 mg, 1.38 mmol) in CH2Cl2 (2 mL) to afford 12 mg of the title product. 1H NMR (300 MHz, DMSO-d6): δ 10.32 (s, 1H), 8.71 (s, 1H), 8.63 (m, 1H), 8.49 (m, 2H), 8.16 (d, 1H), 8.05 (m, 1H), 7.46 (m, 2H), 7.22 (t, J=54 Hz, 1H), 4.42 (d, 2H), 1.55 (s, 9H), 1.05 (d, J=6.6 Hz, 6H); MS [M+H]+: 471.49.
