실험 절차

One embodiment of the present invention relates to the discovery that 3,5-difluoroaniline can be synthesized at high yields and high purity by fluorinating 1,3,5-trichlorobenzene in the presence of a polar solvent to make an intermediate 1,3,5-trifluorobenzene, and then aminating the 1,3,5-trifluorobenzene in the presence of aqueous or anhydrous ammonia to obtain the desired 3,5-difluoroaniline.
