Procedure

In a further embodiment, the present invention relates to a method for the two step preparation of 3,5-difluoroaniline from 1,3,5-trichlorobenzene. First, an amount of 1,3,5-trichlorobenzene is reacted with a fluoride-containing compound to obtain 1,3,5-trifluorobenzene. Second, the 1,3,5-trifluorobenzene is reacted with aqueous ammonia and a metal oxide or metal hydroxide to obtain the product 3,5-difluoroaniline.
