実験手順
A solution of 3,5-difluorophenol (1.3 g, 10 mmol) in dichloromethane (50 ml) at 0° C. was treated with nitric acid (70%, 0.7 ml, 10 mmol). The cooling bath was removed and after 30 min at room temperature the solution washed with water then dried over MgSO4, filtered and evaporated. The product was purified by silica gel chromatography eluting with 20 to 50% ethyl acetate in hexane to yield the title compound, 440 mg.
