Electric Literature of 1260169-02-5, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 1260169-02-5, name is Ethyl 2-aminopyrazolo[1,5-a]pyrimidine-3-carboxylate. This compound has unique chemical properties. The synthetic route is as follows.
2-Aminopyrazolo [1,5-a] pyrimidine-3-carboxylic acidEthyl ester (1.60 g, 7.76 mmol),4-dimethylaminopyridine (0.19 g, 1.55 mmol)And triethylamine (3.25 mL, 23.28 mmol)Dissolved in dichloromethane (15 mL)And di-tert-butyl dicarbonate (3.30 mL, 15.52 mmol) was added thereto.After the resultant reaction solution was stirred at room temperature for 3 hours,Concentrate under reduced pressure.The resulting residue was purified by silica gel column chromatography (100% dichloromethane)The title compound was obtained as a yellow solid (1.24 g, 52.1%).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 1260169-02-5, Ethyl 2-aminopyrazolo[1,5-a]pyrimidine-3-carboxylate.
