Abstract:
A method for preparing N-(1,3,4-oxadiazol-2-yl)arylcarboxamides of formula (I) is described. The substituents therein are radicals such as hydrogen, alkyl, haloalkyl or aryl.

Claim (Index 1):
Method for preparing N-(1,3,4-oxadiazol-2-yl)arylcarboxamide of formula (I) by reacting 2-amino-1,3,4-oxadiazoles of formula (II) with benzoic acids of formula (III), wherein said method is carried out\n a) in the presence of an activating reagent from the group consisting of thionyl chloride, phosgene, diphosgene, mesyl chloride, tosyl chloride, POCl 3 , PCl 5 , oxalyl chloride and C 1 -C 8 -alkyl-OC(O)Cl, and \n (b) in the presence of a base of formula (IV), \n and c) where the substituents are as defined hereinbelow: R 1  is hydrogen, C 3 -C 12 -cycloalkyl, C 1 -C 8 -alkyl, C 1 -C 5 -alkoxy,\n halogen, cyano or phenyl, \n R 2  is hydrogen, C 1 -C 5 -alkyl or halogen, R 3  is hydrogen, C 1 -C 8 -alkyl, C 1 -C 8 -alkylsulphenyl, C 1 -C 8 -alkylsulphinyl\n or C 1 -C 8 -alkylsulphonyl, \n R 4  is C 1 -C 5 -alkyl or C 1 -C 3 -haloalkyl, R 5  is C 1 -C 12 -alkyl or phenyl.
