2-Chloro-4-fluoronitrobenzene Chemical Properties,Usage,Production

Uses

2-Chloro-4-fluoronitrobenzene is used in the synthesis of active pharmaceutical ingredients (APIs), particularly benzothiazole derivatives. 

Synthesis

625-98-9

2106-50-5

(a) 3-Chlorofluorobenzene (240 g, 1.85 mol) was slowly added to a mixture of sulfuric acid (185 g, 1.85 mol) and nitric acid (166 g, 1.85 mol) pre-cooled to -5°C. The reaction was carried out at the same temperature for 13 hours. The reaction temperature was maintained at -5°C with continuous stirring for 3.5 hours, followed by continued stirring at the same temperature for 13 hours. Upon completion of the reaction, benzene (200 mL) and hexane (200 mL) were added to the reaction mixture for extraction. The organic phases were combined and washed sequentially with water (300 mL), sodium carbonate solution (300 mL) and water (300 mL). The organic layer was dried over anhydrous sodium sulfate and the solvent was removed by distillation under reduced pressure. The residue was purified by distillation to give 138 g of the mixed isomer. The 4-nitro isomer was isolated from the mixed isomer by crystallization and filtered to give 3-chloro-4-nitrofluorobenzene (51 g, 16.7% yield) with a melting point of 36°C-38°C.
