Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 632365-54-9, name is Methyl 5-amino-1H-pyrazole-3-carboxylate, A new synthetic method of this compound is introduced below., Recommanded Product: 632365-54-9
With stirring, a mixture of 10 g (0.046 mol) of diethyl sec-butylmalonate, 6.5 g (0.046 mol) of methyl 5-amino-1H-pyrazole-3-carboxylate and 9.4 g (0.051 mol) of tri-n-butylamine was heated at 180 C. for 6 hours. During this time, the ethanol released during the reaction was continuously distilled off. The reaction mixture was then concentred under reduced pressure. This gave 12.2 g (100% of theory) of methyl 5,7-dihydroxy-6-(sec-butyl)-pyrazolo[1,5-a]pyrimidine-3-carboxylate. The product was used for further syntheses without additional purification.
The synthetic route of 632365-54-9 has been constantly updated, and we look forward to future research findings.
