반응 단계

In a 250 ml single-neck flask equipped with a magnetic stirrer and a reflux condenser fitted with a nitrogen bubbler were placed 9.13 g (0.050 moles) of 2-chloro-5-nitrobenzonitrile, 8.55 (0.0515 moles) of 2,3,5,6-tetrafluorophenol, 7.10 g (0.0515 moles) of anhydrous K2CO3, and 75 ml of acetonitrile. The mixture was heated to reflux and held there for 3 hrs. The reaction mixture was then cooled to room temperature and diluted with 150 ml of deionized water. The product separated as a solid. The solid was filtered off, washed thoroughly with water, and air-dried. The air-dried solid was recrystallized from 300 ml of absolute ethanol to give 11.36 g (73% yield) of purified 2-(2,3,5,6-tetrafluorophenoxy)-5-nitrobenzonitrile, mp 152.5°-154.5° C.
