Electric Literature of 6523-49-5,Some common heterocyclic compound, 6523-49-5, name is 4-(1,2,4-Triazol-1-yl)aniline, molecular formula is C8H8N4, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
To a suspension of 9-substituted-2,6-dichloro-9H-purine (8)(2.00 mmol) in a mixture of n-propanol (10 mL) and N,N-diisopropyl-N-ethylamine (6.00 mmol), appropriate amine (2.05 mmol)was added. The suspension was heated while stirring in a sealedtube under an argon atmosphere at 100 C for 2-6 h. The reactionwas checked by TLC using mobile phase toluene-ethylacetate (1:1,v/v). After the completion of the reaction, the reaction mixture wascooled to room temperature and evaporated under reduced pressure.The residue was partitioned between water (50 mL) and dichloromethane (50 mL), and the water phase was extracted twoadditional times with the same volume of dichloromethane. Thecombined organic phases were washed with water and brine andevaporated under reduced pressure. The crude product was crystallizedfrom petroleum ether/ethylacetate (3:1).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-(1,2,4-Triazol-1-yl)aniline, its application will become more common.
