実験手順

To a stirred solution of 2-chloro-4-fluoro-phenol (292 mg, 2.0 mmol) in N,N-dimethylformamide (5 mL) was added sodium hydride (28.8 mg, 1.2 mmol) portionwise at 0° C. under nitrogen and stirred at the same temperature for 15 minutes. To the above mixture was added [5-(5-bromo-6-chloro-pyridine-3-sulfonylamino)-5,6,7,8-tetrahydro-naphthalen-1-yloxy]-acetic acid tert-butyl ester (212 mg, 0.4 mmol) portionwise at 0° C. Then the reaction mixture was heated at 100° C. overnight. After being cooled to room temperature, the reaction was quenched with water (2 mL), and diluted with ethyl acetate (50 mL). The resulting solution was washed subsequently with water (10 mL), 1N sodium hydroxide solution (10 mL), and brine (10 mL). The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo to give {5-[5-bromo-6-(2-chloro-4-fluoro-phenoxy)-pyridine-3-sulfonylamino]-5,6,7,8-tetrahydro-naphthalen-1-yloxy}-acetic acid tert-butyl ester, which was used in the next step without further purification. MS cald. for C27H27BrClFN2O6S 640, obsd. 641 [(M+H)+].
