実験手順

A mixture of 2-(4-(8-Bromo-2-oxo-2,3-dihydro-1H-imidazo[4,5-c]quinolin-1-yl)phenyl)-2-methylpropanenitrile (Intermediate 1, 25 mg, 0.06 mmol) and sodium acetate (5 mg, 0.06 mmol) was heated at 110-120° C. in valproic anhydride (1 ml) for four hours. Reaction mixture was cooled to RT. Water was added and extracted with ethyl acetate. Ethyl acetate layer was washed with brine, dried over sodium sulfate and concentrated. The crude product was purified by column chromatography (silica gel, 2% acetone in chloroform) to obtain the title compound. Yield: 12 mg (38%); 1H NMR (CDCl3, 300 MHz): δ 9.849 (s, 1H), 7.98-8.01 (d, 1H, J=9 Hz), 7.78-7.81 (d, 2H, J=8.7 Hz), 7.63-7.67 (dd, 1H, J=9, 2.1 Hz), 7.54-7.57 (d, 2H, J=8.1 Hz), 7.02-7.03 (d, 1H, J=1.8 Hz), 2.38 (m, 1H), 1.84 (s, 6H), 1.67 (m, 4H), 1.49 (m, 4H), 0.9 (m, 6H); MS: m/z 533 (M+).
