Reaction Steps
The {3-Hydroxy-4-[(4′-trifluoromethylbiphenyl-2-carbonyl)amino]phenyl}acetic acid 2,2-bisethylcarbamoyl-2-phenylethyl ester (195 mg) obtained in Example 3-2was dissolved in chloroform (5 mL), and to this solution was added triethylamine (72 mg). The solution was cooled to 0° C. and triphosgene (35 mg) was added thereto. After stirring for one hour, the reaction solution was washed with water, dried over sodium sulfate and purified by column chromatography on silica gel with hexane:ethyl acetate=1:1 to give the title compound (173 mg) (see Table 59).
