実験手順

Concentrated sulfuric acid (1 mL) was slowly added to a solution of 2-(2-methoxy-6-nitro-phenyl)acetonitrile (200 mg, 1.04 mmol) in 95% ethanol (2 mL). The mixture was heated at reflux overnight then quenched into ice cold water and extracted with diethyl ether (10 mL). The organic phase was washed with water (2×10 mL), dried over anhydrous sodium sulfate and concentrated in vacuo to afford ethyl 2-(2-methoxy-6-nitro-phenyl)acetate (180 mg, 72%).
