Reaction Steps
Concentrated sulfuric acid (1.2 mL) was added to 2-(4-hydroxy-3-propylphenyl)-1,1,1,3,3,3-hexafluoro-2-propanol (500 mg, 1.65 mmol) under ice-cooling. Then, a mixed solution of nitric acid (109 μL) and concentrated sulfuric acid (219 μL) was added dropwise at 30 to 35° C., followed by stirring at 40° C. for three hours. The reaction solution was cooled and then added dropwise to ice water. After neutralization to pH 7 with a sodium hydroxide solution (1 mol/L), the neutralized solution was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=3:1) to obtain 94.3 mg of the title compound (yield: 16%) as a red orange oil.
