Versuchsvorschrift

Add ethyl 2-[4-(hexafluoro-2-methoxy-2-propyl)-2,6-dimethylphenoxy]acetate (2.6 g=6.7 mmol) to 30 ml 1.0 N NaOH. Add 20 ml methanol and reflux 3 hours. Acidify with 1.0 N HCl and extract with ether. Dry, concentrate and recrystallize the combined extracts from hexane to obtain, as a white solid, 2-[4-(hexafluoro-2-methoxy-2-propyl)-2,6-dimethylphenoxy]acetic acid, m.p. 105°-108° C.
