実験手順
To a mixture of 3.60 g of mixture containing 4-(heptafluoroisopropyl)phenol, 8 ml of acetic acid, and 2.5 g of concentrated sulfuric acid, a mixture of 1.05 g of 69% nitric acid and 1 ml of acetic acid was added dropwise while ice-cooling, and then stirred at room temperature for two hours. The reaction mixture was poured into water, and extracted with ethyl acetate three times. The combined organic layers were washed with a saturated sodium chloride solution, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 2.96 g of 4-(heptafluoroisopropyl)-2-nitrophenol.
