Versuchsvorschrift

To ethyl 2-[4-(hexafluoro-2-hydroxy-2-propyl)-2,6-dimethylphenoxy]acetate (6.0 g=16 mmol) in 60 ml dry dimethylformamide add sodium hydride dispersion in mineral oil (0.85 g=18 mmol). Stir 1 hour and add methyl iodide (3.0 g=21 mmol). Let stir 2 hours and partition between water and ether. Wash the ether layer with water, dry and concentrate. Recrystallize from ether-hexane to obtain ethyl 2-[4-(hexafluoro-2-methoxy-2-propyl)-2,6-dimethylphenoxy]acetate, m.p. 97°-98° C.
