実験手順

Stir together for 16 hours a mixture of ethyl 2-[4-(hexafluoro-2-hydroxy-2-propyl)-2,6-dimethylphenoxy]acetate (7.1 g=19 mmol) and 125 ml 1.0 N NaOH. Acidify with concentrated HCl and extract with ether. Dry and concentrate the ether. Recrystallize from ether-hexane to obtain, as white crystals, 2-[4-(hexafluoro-2-hydroxy-2-propyl)-2,6-dimethylphenoxy]acetic acid, m.p. 118°-120° C.
