A process for preparing arylcarboxamides of the formula (I) n n n n n n n n n n where n Ar =a mono- to trisubstituted phenyl, pyridyl or pyrazolyl ring, where the substituents are selected from halogen, C i -C 4 -alkyl and C 1 -C 4 -haloalkyl; n M =thienyl or phenyl, which may bear a halogen substituent; n Q =direct bond, cyclopropylene, fused bicycio[2.2.1]heptane or bicyclo[2.2.1]heptene ring; n R 1 =hydrogen, halogen, C 1 -C 6 -alkyl, C 1 -C 4 -alkoxy, C 1 -C 4 -haloalkoxy, mono- to trisubstituted phenyl, where the substituents are selected from halogen and trifluoromethylthio, or cyclopropyl; n by reacting an acid chloride of the formula (II) n n n n n n n n n n with an arylamine (III) n n n n n n n n n n in a suitable nonaqueous solvent, wherein, in the absence of an auxiliary base, n a) the acid chloride (II) is initially charged, n b) a pressure of from 0 to 700 mbar is established, n c) the arylamine (III) is metered in in an approximately stoichiometric amount and n d) the product of value is isolated. |
