Participants

Reaction Steps

A solution of 4-fluoro-2-hydroxy-1-nitrobenzene (100 mg, 0.637 mmol) in N,N-dimethylformamide (3.2 mL) was added with potassium carbonate (132 mg, 0.955 mmol), then added with methyl iodide (48 μL, 0.764 mmol) under ice-cold conditions, and stirred at room temperature for 1 hour. The reaction solution was further added with potassium carbonate (132 mg, 0.955 mmol), then with methyl iodide (48 μL, 0.764 mmol) under ice-cold conditions, and stirred at 60° C. for 1 hour. The reaction solution was added with water and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo. 4-fluoro-2-methoxy-1-nitro-benzene (118 mg, yield >100%) was obtained as a yellow oil.
