Versuchsvorschrift

0.15 g of ethyl 3-[3-(aminomethyl)-4-methoxyphenyl]-2-isopropoxypropanoate was dissolved in 5 ml N,N-dimethylformamide, and 0.2 ml pyridine and 0.24 g of 2-fluoro-4-(trifluoromethyl)benzoate chloride were added, followed by stirring at room temperature for 12 hours. Water was added to the reaction solution, followed by extracting with ethyl acetate The extract was washed with brine, dried over anhydrous magnesium sulfate and the solvent was evapoarated. The residue was subjected to silica gel column chromatography, and from fractions eluted with ethyl acetate-hexane (1:2), 0.2 g of ethyl 2-isopropoxy-3-[4-methoxy-3-({[2-fluoro-4-(trifluoromethyl)benzoyl]amino}methyl)phenyl]propanoate was obtained as a pale yellow oil. This product was treated in the same manner as in Example 1d), to give 0.15 g of 2-isopropoxy-3-[4-methoxy-3-{[2-fluoro-4-(trifluoromethyl)benzoyl]amino}methyl)phenyl]propanoic acid as a pale yellow solid.
