실험 절차

To 2,6-dimethyl-4-(hexafluoro-2-propyl)phenol [Farah, et al, J. Org. Chem., 30, 1003 (1965)], (10.0 g=35 mmol) in 100 ml acetonitrile add ethyl bromoacetate (6.9 g=42 mmol) and potassium carbonate (9.7 g=69 mmol). Stir 5 hours, filter and concentrate. Partition between ether and 1.0 N HCl. Dry and concentrate the ether extract. Recrystallize from ether-hexane to obtain, as white crystals, m.p. 99°-101° C., ethyl 2-[4-(hexafluoro-2-hydroxy-2-propyl)-2,6-dimethylphenoxy]acetate.
