Reaction Steps

To a solution of 2-(4-(8-bromo-2-oxo-2,3-dihydro-1H-imidazo[4,5-c]quinolin-1-yl)phenyl)-2-methylpropanenitrile (Intermediate 1, 100 mg, 0.25 mmol) in dry DMF (5 mL), sodium hydride (12 mg, 0.27 mmol) was added at 0° C. under nitrogen atmosphere. After 15 minutes morpholine-4-carbonyl chloride (56.1 mg, 0.37 mmol) was added, and the reaction mixture was heated at 60° C. for 48 hours. The reaction mixture was concentrated in vacuum. The crude product was purified by column chromatography (silica gel, 3% acetone in chloroform) to obtain the title compound. Yield: 15 mg (11.73%); 1H NMR (CDCl3, 300 MHz): δ 9.09 (s, 1H), 7.973-8.004 (d, 1H, J=9.3 Hz), 7.772-7.8 (d, 2H, J=8.4 Hz), 7.621-7.658 (dd, 1H, J=9 Hz, 2.1 Hz), 7.517-7.545 (d, 2H, J=8.4 Hz,), 7.057-7.064 (d, 1H, J=2.1 Hz), 3.67 (t, 4H,), 3.26 (t, 4H), 1.84 (s, 6H); MS: m/z 520 (M+).
