Reaction Steps

To 2-methoxy-6-methylphenol (27.6 g=0.20 mol) in 300 ml toluene, add aluminum chloride (4.0 g=30 mmol). Bubble in hexafluoroacetone (47 g=0.28 mol) over 7 hours. Heat the reaction mixture in a steel bomb 16 hours at 120° C. Cool, and pour the contents onto 1.0 N HCl. Extract with ether. Wash the ether layer with 1.0 N NaOH. Acidify the basic aqueous layer with concentrated HCl, extract with ether, dry, concentrate and distill to obtain a fraction boiling at 71°-74° C./0.1 mm. Crystallize from cold hexane to obtain, as a solid, m.p. 44°-45° C., 4-(hexafluoro-2-hydroxy-2-propyl)-2-methoxy-6-methylphenol.
