This invention provides an azomethine compound that can realize a good coupling reaction and, at the same time, can significantly reduce the production cost of the azomethine compound, the azomethine compound comprising a pyridine ring bonded through a nitrogen atom to a 1H-pyrazolo[1,5-b][1,2,4]triazole ring. The azomethine compound is represented by formula (M-I):
wherein R1 represents a phenyl group or a naphthyl group optionally substituted by an alkyl group or a halogen; and R2 and R3 each independently represent a C2-4 (number of carbon atoms) alkyl group.
本发明提供了一种偶氮亚甲基化合物,可实现良好的偶联反应,同时可显著降低偶氮亚甲基化合物的生产成本,偶氮亚甲基化合物包括一个吡啶环,该吡啶环通过一个氮原子与一个1H-吡唑并[1,5-b][1,2,4]三唑环键合。偶氮亚甲基化合物用式(M-I)表示:
其中 R1 代表苯基或任选被烷基或卤素取代的萘基;R2 和 R3 各自独立地代表 C2-4(碳原子数)烷基。
