Related Products of 584-13-4, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 584-13-4, name is 4H-1,2,4-Triazol-4-amine belongs to Triazoles compound, it is a common compound, a new synthetic route is introduced below.
REFERENTIAL EXAMPLE 2 STR7 2.52 Grams of 4-amino-1,2,4-triazole was added little by little to a dimethylsulfoxide suspension of 1.2 g of sodium hydride at room temperature. After stirred for 3 hours at room temperature, 1.21 g of 4-fluorobenzonitrile was added thereto all at a time, and stirring was continued for further one hour. Water was added to the reaction solution, and the mixture was then extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was removed by distillation under reduced pressure. The crystals obtained were washed with ethyl acetate to give 1.09 g of 4-[(4-cyanophenyl)amino]-4H-1,2,4-triazole. Nuclear Magnetic Resonance Spectrum (DMSO-d6, TMS internal standard) delta: 6.57 (2H, d, J=9 Hz), 7.69 (2H, d, J=9 Hz), 8.83 (2H, s) Mass Spectrometry (m/z): 185 (M+)
The synthetic route of 4H-1,2,4-Triazol-4-amine has been constantly updated, and we look forward to future research findings.
