Reaction Steps
To 1.9 mL (24.74 mmol) of dimethyl formamide dissolved in 20 mL benzene was added 2.7 mL (37.11 mmol) thionyl chloride. The mixture was stirred for 10 minutes and 5.0 g (24.74 mmol) 4-fluoro-2,6-dinitrophenol was added. The mixture was refluxed 6 hours, cooled and concentrated under reduced pressure. The residue was recrystallized from ethanol to give 2-chloro-5-fluoro-1,3-dinitro-benzene (5.39 g).
