Related Products of 1455-77-2, New Advances in Chemical Research in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic,A common heterocyclic compound, 1455-77-2, name is 3,5-Diamino-1,2,4-triazole, molecular formula is C2H5N5, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
Then, an amidation step is carried out, the reaction equation being as follows: The 1.49g (15mmol, 1eq) of the compound of Formula III-1 3,5-amino-1,2,4-triazole, 3.64 g (36 mmol, 2.4 eq) of triethylamine were dissolved in 50 mL of dichloromethane,50 mL of a dichloromethane solution containing 9.39 g of the compound shown by the formula 11-1 (4- (4′-nitrophenyl) benzoyl chloride) was slowly added dropwise at 0 ° C. After completion of the dropwise addition,The reaction solution was allowed to react at room temperature for 24 h,Subsequently, the reaction solution was washed with 200 mL of pure water, After the layers were separated, the organic phase was washed twice with saturated sodium carbonate solution and then dried over anhydrous magnesium sulfate,The organic phase was evaporated to give a crude product,The crude product was recrystallized to give 6.52 g of the compound of formula IV-1,The yield was 80percent.
I am very proud of our efforts over the past few months and hope to 3,5-Diamino-1,2,4-triazole help many people in the next few years.
