PROCEDURE
实验过程
0.41 g of 1,3-difluoro-4,6-dinitrobenzene was dissolved in 8 ml of 0.5 N aqueous sodium hydroxide solution and refluxed for 2 hours. After cooling, it was diluted with water and extracted three times with diethyl ether. The aqueous phase was made acidic by adding 1N hydrochloric acid and extracted with diethyl ether. The organic phase was dried on sodium sulfate and concentrated by evaporation in a vacuum.
