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 (24.4 mg, 0.36 mmol) in dichloromethane (6 ml) was added benzenesulfonyl chloride (31.8 mg, 0.18 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 organic layer was dried on sodium sulfate and evaporated to dryness to obtain the title compound. Yield: 20 mg (29.7%); 1H NMR (CDCl3, 300 MHz): δ 9.59 (s, 1H), 8.198-8.227 (d, 2H, J=8.7 Hz), 7.958-7.989 (d, 1H, J=8.7 Hz), 7.70-7.723 (d, 2H, J=6.9 Hz), 7.57-7.69 (m, 4H), 7.40-7.436 (d, 2H, J=8.7 Hz), 6.97-6.981 (d, 1H, J=2.1 Hz), 1.79 (s, 6H).
