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. 6825-71-4, name is Ethyl 3,5-diamino-1H-pyrazole-4-carboxylate, A new synthetic method of this compound is introduced below., Quality Control of Ethyl 3,5-diamino-1H-pyrazole-4-carboxylate
Sodium ethoxide (33.2g) at room temperatureEthanol solution (500mL)3,5-Diamino-1H-pyrazole-4-carboxylic acid ethyl ester (20.8 g) was added in sequence.1,3-Dimethylpyrimidine-2,4(1H,3H)-dione (17.0 g).After the completion of heating to 90 C reaction12 hours.After the reaction is completed,The pH was adjusted to pH 7 with 1N hydrochloric acid at room temperature.Collect solids,Ethanol wash,Dry to give the title compound (18.4 g).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
