実験手順
A mixture of 3-(2,4-difluorophenoxy)-4-nitrobenzoic acid (1.0 g) and sulfuric acid (3 drops) in ethanol (5 ml) was refluxed for 8 hours. Ethanol was evaporated under reduced pressure, and the residue was dissolved in ethyl acetate, washed with a saturated aqueous solution of sodium bicarbonate, dried over magnesium sulfate, and concentrated to give pale brown needles of ethyl 3-(2,4-difluorophenoxy)-4-nitrobenzoate (1.1 g).
