- reaction is carried out according to the invention without auxiliary base in an organic solvent which is substantially anhydrous.
- a low water content is understood to mean about 0.5 g to 5 g of water per mole of acid chloride (II) used. Larger amounts of water should be avoided, since the water would lead to an increased consumption of starting materials.
- Useful solvents include, for example, aromatic hydrocarbons such as
- Particularly preferred solvents are the aromatic hydrocarbons, in particular toluene and o-, m-, p-xylene.
- the acid chloride (II) is introduced, the desired pressure is established and the arylamine (III) is metered in.
- metered addition is meant both the portionwise and continuous addition of (III) a) to the surface of the solution of (II) or b) directly into the solution of (II), referred to as "submerged reaction”.
- the pressure is usually chosen so that the reaction mixture boils.
- the reaction is carried out at a pressure between 0 and 700 mbar and a reaction temperature of 20 to 12O 0 C, preferably at 200 to 600 mbar and 70 to 100 0 C, in particular 350 to 450 mbar and 80 to 9O 0 C.
