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. 20780-72-7, name is 4-Bromoisatin, A new synthetic method of this compound is introduced below., name: 4-Bromoisatin
General procedure: (The reagents were purchased fromAdamas and used without further purification.) A dry 3-mL flask was chargedwith relevant isatin 5 (0.3 mmol), tert-butyl 2-aminoacetate hydrochloride 7(0.3 mmol) and benzophenone imine 8 (0.36 mmol). The reaction mixture wasstirred at room temperature for the corresponding time. After the completionof the reaction, the reaction mixture was directly purified by silica gelchromatography (ethyl acetate/petroleum ether = 1:4) to give product 6. Asolution of 6 in EA/TFA (10:1) was stirred in a 10-mL flask under roomtemperature for 3 h. The solvent was removed under vacuum. The residue wasrecrystallized in diethyl ether/petroleum ether to give product 9.
The synthetic route of 20780-72-7 has been constantly updated, and we look forward to future research findings.
