Reaction Conditions

Reaction Steps

To a mixture of 23 ml of methanol and 3.6 ml of 2 N aqueous potassium hydroxide solution was added 2.26 g of N-acetyl-N-(2-methoxycarbonylbenzyl)-2-phenoxyaniline synthesized in the same manner as in Example 2, followed by stirring at 60° C. for an hour. The reaction mixture was concentrated under reduced pressure, water was added to the residue, and the mixture was made acidic with 2 N hydrochloric acid and extracted with ethyl acetate. The extract was washed with a saturated aqueous sodium chloride solution and dried over anhydrous sodium sulfate. After removal of the drying agent by filtration, the solvent was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (eluent; ethyl acetate-hexane=1:1) to give 2.01 g of N-acetyl-N-(2-carboxybenzyl)-2-phenoxyaniline as an oil.
