Versuchsvorschrift

To a solution of 2-(4-(8-methyl-2-oxo-2,3-dihydro-1H-imidazo[4,5-c]quinolin-1-yl)phenyl)-2-methylpropanenitrile (Intermediate 3, 100 mg, 0.29 mmol) and triethylamine (60 mg, 0.58 mmol) in dichloromethane (6 ml) was added 2-methyl-5-nitrobenzene-1-sulfonyl chloride (103.35 mg, 0.44 mmol) at 0° C. The reaction was stirred at RT for 3 hours. The reaction mixture was poured into cold water and 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, 2% acetone in chloroform) to obtain the title compound. Yield: 20 mg (12%); 1H NMR (CDCl3, 300 MHz): δ 9.560 (s, 1H), 9.155-9.163 (d, 1H, J=2.4 Hz), 8.384-8.420 (dd, 1H, J=8.4, 2.4 Hz), 8.050-8.079 (d, 1H, J=8.7 Hz), 7.696-7.724 (d, 2H, J=8.4 Hz), 7.538-7.564 (d, 1H, J=7.8 Hz), 7.458-7.486 (d, 3H, J=8.4 Hz), 6.708 (s, 1H), 2.760 (s, 3H), 2.236 (s, 3H), 1.742 (s, 6H); MS: m/z 542 (M+).
