実験手順
3-Nitro-4-phenylphenol (215 mg, 1.0 mmol) was dissolved in N,N-dimethylformamide (5 mL) and tert-butyl 2-bromoacetate (292 mg, 1.5 mmol) was added thereto. After stirring at 80° C. for 18 hours, the reaction solution was extracted with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by flash column chromatography to obtain tert-butyl 2-(3-nitro-4-phenylphenoxy)acetate (370 mg).
