A process for preparing arylcarboxamides of the formula (I) where Ar =a mono- to trisubstituted phenyl, pyridyl or pyrazolyl ring, where the substituents are selected from halogen, Ci-C4-alkyl and C1-C4-haloalkyl; M =thienyl or phenyl, which may bear a halogen substituent; Q =direct bond, cyclopropylene, fused bicycio[2.2.1]heptane or bicyclo[2.2.1]heptene ring; R1 =hydrogen, halogen, C1-C6-alkyl, C1-C4-alkoxy, C1-C4-haloalkoxy, mono- to trisubstituted phenyl, where the substituents are selected from halogen and trifluoromethylthio, or cyclopropyl; by reacting an acid chloride of the formula (II) with an arylamine (III) in a suitable nonaqueous solvent, wherein, in the absence of an auxiliary base, a) the acid chloride (II) is initially charged, b) a pressure of from 0 to 700 mbar is established, c) the arylamine (III) is metered in in an approximately stoichiometric amount and d) the product of value is isolated.
