実験手順

20 ml of a 3N-sodium hydroxide aqueous solution was added to 9.5 g of methyl 4-cyano-2-(4-hydroxyphenoxy)methylbenzoate obtained in Reference example 22 dissolved in 80 ml of methanol and the mixture was stirred at room temperature for 1.5 hours. After completion of the reaction, the solvent was removed under reduced pressure, water was added to the residue and the mixture was washed with diethyl ether and then adjusted to about pH 2 with conc. sulfuric acid. Crystals precipitated were collected by filtration and dissolved in ethyl acetate and the organic layer was washed with a saturated saline solution and then dried over anhydrous sodium sulfate. The solvent was removed from the solution to obtain 5.2 g of the title compound.
