Synthesis
680-15-9
3460-18-2
251115-21-6
To a solution of N-methylpyrrolidone (40 mL) in 2,5-dibromonitrobenzene (5 g, 17.8 mmol) was sequentially added methyl fluorosulfonyl difluoroacetate (4.5 mL, 35.6 mmol) and cuprous iodide (I). The reaction mixture was stirred in an oil bath at 80°C overnight. Upon completion of the reaction, activated carbon was added to decolorize the reaction solution, which was diluted with saturated saline and subsequently extracted with ethyl acetate (3 x 30 mL). The organic phases were combined, dried with anhydrous magnesium sulfate and concentrated under reduced pressure to remove the solvent. The crude product was purified by fast column chromatography (eluent: petroleum ether/ethyl acetate, gradient 0-100%) to give 4-bromo-2-nitrobenzotrifluoromethylbenzene (4.1 g, 85% yield) as a yellow oil.
