Electric Literature of 1260243-04-6, 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. 1260243-04-6, name is Ethyl 5-amino-1H-pyrazole-4-carboxylate belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
EXAMPLE 53 4,5,6,7-Tetrahydropyrazolo[1,5-a]pyrimidine-3-carboxylic acid, ethyl ester A stirred mixture of 10.88 g of 5-amino-4-pyrazolecarboxylic acid, ethyl ester, 11.51 g of malonaldehyde bis(dimethyl acetal) and 100 ml of glacial acetic acid was heated at reflux for 16 hours, then worked up as described in Example 50 to give 7.8 g of pyrazolo[1,5-a]pyrimidine-3-carboxylic acid, ethyl ester.
The synthetic route of Ethyl 5-amino-1H-pyrazole-4-carboxylate has been constantly updated, and we look forward to future research findings.
