Procedure

To a solution of methyl 4-(2-trifluoroacetylamino-5-chlorophenoxymethyl)benzoate (300 mg; prepared in Reference Example 6.) in mixture of THF-MeOH (4 ml+10 ml), a solution of sodium carbonate (440 mg) in water (2 ml) was added. The solution was stirred for 8 hours at 60° C. and overnight at room temperature. The reaction mixture was poured into diluted HCl and extracted with ethyl acetate. The organic layer was washed, dried over and concentrated under the reduced pressure. The residue was purified on silica gel column chromatography (AcOEt-benzene) to give the title compound (194 mg) having the following physical data.
