Summary:PROBLEM TO BE SOLVED: To provide: a new benzotriazole compound which has a large molecular weight, hardly causes volatile loss even in high-temperature processing and can be easily produced industrially; and a method for producing the same.SOLUTION: There is provided a method for producing a benzotriazole compound by carrying out a coupling reaction using a compound represented by the formula (II) and a diazonium salt of an amine represented by the formula (III), followed by further reduction to obtain a benzotriazole represented by the formula (I). (Yrepresents an alkyl group, an aryl group or an aralkyl group; and Yrepresents H or a halogen atom.)SELECTED DRAWING: None 【課題】分子量が大きく、高温加工においても揮発減量し難く、工業的に製造が容易な新規のベンゾトリアゾール化合物及びその製造方法の提供。【解決手段】式（ＩＩ）で表される化合物と、式（ＩＩＩ）で表されるアミンのジアゾニウム塩とを用いてカップリング反応を行い、さらに還元させることによって式（Ｉ）で表されるベンゾトリアゾールを得る、ベンゾトリアゾール化合物の製造方法。（Ｙ１はアルキル基、アリール基又はアラルキル基；Ｙ２はＨ又はハロゲン原子）【選択図】なし
