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, 50 mg, 0.12 mmol) and triethylamine (18 mg, 0.18 mmol) in dichloromethane (6 ml) was added (isocyanatomethyl)benzene (24.57 mg, 0.18 mmol). The reaction mixture was stirred at RT for 2 hours. Then the reaction mixture was poured on to water. The organic layer was separated. The aqueous layer was extracted with dichloromethane. The combined organic layer was washed with brine, dried over sodium sulfate and evaporated to dryness. The crude product was purified by column chromatography (silica gel, 1% MeOH in chloroform) to obtain the title compound. Yield: 18 mg (20%); 1H NMR (CDCl3, 300 MHz): δ 9.89 (s, 1H), 8.95 (t, 1H), 7.978-8.008 (d, 1H, J=9 Hz), 7.762-7.790 (d, 2H, J=8.4 Hz), 7.614-7.651 (dd, 1H, J=9, 1.8 Hz), 7.500-7.529 (d, 2H, J=8.7 Hz), 7.27-7.38 (m, 5H), 7.018-7.025 (d, 1H, J=2.1 Hz), 4.642-4.611 (d, 2H, J=5.7 Hz), 1.82 (s, 6H); MS: m/z 540 (M+).
