    摘要： A process for producing an alkoxytetrazol-1-ylbenzaldehyde compound represented by the general formula (2): (wherein A1 represents alkoxy and A2 represents hydrogen, alkyl, or fluoroalkyl), characterized by reacting a 1-(alkoxyphenyl)-1H-tetrazole compound represented by the general formula (1): (wherein A1 and A2 are the same as defined above) with hexamethylenetetramine in a sulfonic acid solvent and subsequently hydrolyzing the reaction product. Thus, an alkoxytetrazol-1-ylbenzaldehyde compound can be safely and efficiently produced by formylating a 1-(alkoxyphenyl)-1H-tetrazole compound.

    摘要翻译： 通式（2）表示的烷氧基四唑-1-基苯甲醛化合物的制备方法：其中A1代表烷氧基，A2代表氢，烷基或氟代烷基，其特征在于使1-（烷氧基苯基）-1H-四唑化合物 （1）表示的化合物：（其中A1和A2与上述定义相同）与六亚甲基四胺在磺酸溶剂中反应，随后水解反应产物。 因此，通过将1-（烷氧基苯基）-1H-四唑化合物甲酰化，可以安全有效地制备烷氧基四唑-1-基苯甲醛化合物。

    摘要： A process for the production of N-aryl-2,2,2-trifluoro- acetimidoyl chloride represented by the general formula (2) by reacting a 2,2,2-trifluoro-N-arylacetamide represented by the general formula (1) with both at least one member selected from the group consisting of phosphorus oxychloride and diphenyl- phosphoric acid chloride and a tertiary amine in an organic solvent; and a process for the production of 1-aryl-5 -(trifluoromethyl)-1H-tetrazoles represented by the general formula (4) by reacting an N-aryl-2,2,2-trifluoroacetimidoyl chloride represented by the general formula (2) with an azide in an aromatic hydrocarbon solvent in the presence of an amine salt.
