    摘要: The invention relates to a method for producing N-(5-amino-2-cyano-4-fluoro-phenyl)-sulphonamides. In a first step, 2-amino-4,5-difluoro-benzonitrile is reacted with sulphonic acid halogenides in the presence of an acid acceptor and a diluting agent at temperatures between 0 °C and 150 °C. In a second step, the N-(2-cyano-4,5-difluoro-phenyl)-sulphonamide and/or N-(2-cyano-4,5-difluoro-phenyl)-sulphonamides are reacted, either in the pure state or mixed, with ammonia in the presence of a diluting agent at temperatures between 100 °C and 200 °C. The invention also relates to new intermediate products of this method.
