Reaction Steps

To a suspension of 2-(4-(8-bromo-2-oxo-2,3-dihydro-1H-imidazo[4,5-c]quinolin-1-yl)phenyl)-2-methylpropanenitrile (Intermediate 1, 0.040 g, 0.10 mmol) and potassium fluoride (0.009 g, 0.147 mmol) in dry benzene (6 ml) was added allylisocyanate (0.010 g, 0.10 mmol) at RT. The reaction was stirred at reflux temperature for 6 hours. The reaction mixture was cooled and poured into cold water, extracted with ethyl acetate (2×20 ml). Organic layer was washed with water dried over sodium sulfate and concentrated. The crude product was triturated with ethyl acetate, filtered and filtrate was purified by column chromatography (silica gel, 2% acetone in chloroform) to obtain the title compound. Yield: 0.020 g (41%); 1H NMR (DMSO-d6, 300 MHz): δ 9.653 (s, 1H), 8.723-8.761 (t, 1H), 7.971-8.001 (d, 1H, J=9 Hz), 7.874-7.903 (d, 2H, J=8.7 Hz), 7.769-7.798 (d, 2H, J=8.7 Hz), 7.723-7.761 (dd, 1H, J=9, 2.1 Hz), 6.808-6.814 (d, 1H, J=1.8 Hz), 5.904-5.996 (m, 1H), 5.234-5.296 (dd, 1H, J=17.1, 1.2 Hz), 5.134-5.173 (dd, 1H, J=10.5, 1.2 Hz), 4.010-4.045 (t, 2H), 1.806 (s, 6H); MS: m/z 492 (M+).
