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. 37622-90-5, name is Ethyl 4-pyrazolecarboxylate, A new synthetic method of this compound is introduced below., Formula: C6H8N2O2<\/a><\/p>\n

To a solution of ethyl 1H-pyrazole-4-carboxylate (31 g) and sodium acetate (120 g) in a mixed solvent of ethanol (200 mL) and water (300 mL) was added bromine (140 g), and the mixture was stirred at room temperature for 10 hr. To the reaction mixture was added sodium thiosulfate (180 g), and the mixture solvent was evaporated under reduced pressure. The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to give the title compound (65 g). (1090) MS (ESI+): [M+H]+ 296.7<\/p>\n

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.<\/p>\n","protected":false},"excerpt":{"rendered":"
