ABSTRACT:
The present invention relates to a process for producing an N-aryl-2,2,2-trifluoroacetimidoyl chloride represented by Formula (2):the process comprising the step of reacting in an organic solvent a tertiary amine, a 2,2,2-trifluoro-N-arylacetamide represented by Formula (1):and at least one member selected from the group consisting of phosphorus oxychloride and diphenyl chlorophosphate; and a process for producing a 1-aryl-5-(trifluoromethyl)-1H-tetrazole represented by Formula (4):the process comprising the step of reacting in an aromatic hydrocarbon solvent, in the presence of an amine salt, an N-aryl-2,2,2-trifluoroacetimidoyl chloride represented by Formula (2) shown above and an azide.
