<p>A method of preparing 2,4-difluoroaniline by reacting 2,4,5-trichloronitrobenzene with a fluorinating agent in the presence of a solid-liquid phase interface, and utilizing a phase transfer catalyst to form 2,4-difluoro-5-chlorinitrobenzene, followed by hydrogenation with hydrogen in the presence of a hydrogenation catalyst to form 2,4-difluoroaniline.</p> |
