実験手順

5.5 g of α-chloro-2-fluoro-3,4-dimethoxytoluene and 4.05 g of potassium acetate are stirred at 80° for 25 hours in 50 ml of dimethylformamide. The reaction mixture is subsequently poured into 150 ml of ice-water and extracted with ether. The ether phases are washed with sodium chloride solution, dried over sodium sulfate and evaporated. 2-fluoro-3,4-dimethoxybenzyl acetate is obtained as an oil.
