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. 37687-24-4, name is Diethyl 3,5-pyrazoledicarboxylate, A new synthetic method of this compound is introduced below., Computed Properties of C9H12N2O4
To a solution of diethyl 1H-pyrazole-3,5-dicarboxylate (0.25 g, 1.18 mmol) in acetone (10 ml) were added 2-bromo-1-(3-fluoro-4-methylphenyl)ethanone (0.33 g, 1.41 mmol) and potassium carbonate (0.41 g, 2.95 mmol). The mixture was stirred at RT over night. After filtering off the sol- ids, the filtrate was concentrated and the residue dried in vacuo to give 0.48 g (99% of theory, 87% purity) of the title compound. This compound was used without further purification. LC/MS [Method 3]: Rt = 2.07 min; MS (ESIpos): m/z = 363 [M+H]+.
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.
