To a solution of 3-chloro-5-fluoro-4-(quinolin-3-yloxy)phenylamine (50.2) (0.420 g) in pyridine (2.2 mL), was added 2,4-dichloro-5-methylbenzenesulfonylchloride 0.360 g. The mixture was stirred at room for 1 h. The reaction mixture was purified directly by column chromatography (silica gel, AcOEt:hexane=1:3). The product was triturated by hexane to give title compound (0.522 g). Yield 73% as a solid. 1H NMR (300 MHz/CDCl3) δ 2.43 (3H, s), 7.05 (1H, d, J=2.6 Hz), 7.09-7.11 (1H, m), 7.21 (1H, d, J=2.6 Hz), 7.36 (1H, brs), 7.49-7.66 (4H, m), 7.96 (1H, s), 8.10 (1H, d, J=8.2 Hz), 8.80 (1H, brs). MS (M+H) 511. mp 187° C.
