Synthetic Route of 63666-11-5, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 63666-11-5 as follows.
A suspension of ethyl 5-amino-lH-l,2,4-triazole-3-carboxylate in acetic anhydride was refluxed for 30 min. Excess acetic anhydride was evaporated. Water was added to the residue and the mixture was stirred overnight. The colourless product was filtered off, washed with water and dried to obtain 0.134 g (53% yield) of the product. 1H-NMR (40 MHz, DMSO-d6): 1.35 (3H. t. OCH2CH3), 2.12 (3H, s, COC), 4.3 (2H, q, OCH2CH3), 11.71 (1H, s, NHCO), 13.74 (1H, s, NH-triazole)
According to the analysis of related databases, 63666-11-5, the application of this compound in the production field has become more and more popular.
