Application of 41253-21-8, These common heterocyclic compound, 41253-21-8, name is Sodium 1,2,4-triazol-1-ide, its 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.
Compound (II-1) (48.6mmol) N, N- dimethylacetamide ( 30 mL) And it was dissolved in water (2.3mL), and the temperature was raised to 65C . Here , compound (III-1) (63.3mmol), TMSOB (58.4mmol) and sodium hydroxide ( 12. 0mmol) was added and stirring . After 7 hours , 2 hours reaction is performed by elevating the temperature of the reaction temperature to 85C It was . After completion of the reaction , water was added to the reaction mixture, and the mixture was extracted with toluene to obtain a compound (I-1). 82.0% yield .
The synthetic route of 41253-21-8 has been constantly updated, and we look forward to future research findings.
