実験手順

To a solution of 3-(4-Amino-2,6-dichloro-phenoxy)-quinoline-8-carboxylic acid methyl ester (315) (1.26 mmol) in Pyridine (0.15 ml, 1.80 mmol) and CH2Cl2 (5 ml), was added 2,4-Dichlorobenzenesulfonyl chloride (381 mg, 1.55 mmol). The mixture was stirred at room temperature for 12 hr. Sat NaHCO3 was added to the reaction mixture, which was then extracted twice with AcOEt. Organic layer was washed by Brine, dried over MgSO4, and concentrated. The crude residue was purified by column chromatography (Hexane/AcOEt=2/1, 80 g of silica gel) to afford compound 182 (506 mg, 70%) as a white solid.
