2,3-Difluoroaniline Chemical Properties,Usage,Production
Chemical Properties
clear light orange liquid
Uses
2,3-Difluoroaniline was used in the synthesis of ethyl 2-arylamino-4-trifluoromethylpyrimidine-5-carboxylate.
Uses
intermediate for liquid crystal and drugs
Synthesis
1481-57-8
4519-40-8
The general procedure for the synthesis of 2,3-difluoroaniline from 2,3-dibromo-5,6-difluoronitrobenzene was as follows: first, 0.638 g (2.01 mmol) of 2,3-dibromo-5,6-difluoronitrobenzene was dissolved in 4 mL of methanol. Subsequently, 48.4 mg of 10% Pd/C (50% wet) catalyst and 6.2 mg (0.06 mmol) of triethylamine were added to the solution. The atmosphere in the reaction vessel was replaced with hydrogen and the reaction mixture was stirred at 50 °C for 2 h under slight hydrogen pressure. The reaction mixture was analyzed by HPLC, which showed the presence of 2.2 area% of 2,3-dibromo-5,6-difluoroaniline as a residual intermediate. The reaction was continued under the same conditions for 0.5 hours. After completion of the reaction, the catalyst was removed by filtration. The resulting liquid was quantitatively analyzed by HPLC and the yield of 2,3-difluoroaniline was measured to be 93% and the intermediate 2,3-dibromo-5,6-difluoroaniline was completely consumed.
