Reaction Steps
Catechol (103.8 g, 0.94 mol) and potassium carbonate (129.9 g, 0.94 mol) are added to a solution of 2,4-difluoronitrobenzene (50.0 g, 0.314 mol) in acetonitrile. The reaction mixture is stirred at 28° C. for 24 hours, poured into brine and extracted with ether. The organic extract is washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo to obtain a brown gum. Flash chromatography of the gum using silica gel and a 10% hexanes in methylene chloride solution gives the title product as a yellow solid (43 g) which is identified by 1HNMR spectral analysis.
