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. 22190-33-6, name is 5-Bromoindoline, A new synthetic method of this compound is introduced below., category: indolines-derivatives
To a stirred solution of 5-bromo-indoline (3.0 g, 15 mmol) in acetonitrile (100 ml), was added DMAP (0.185 g, 1.522 mmol) and di-tert-butyl dicarbonate (3.98 g, 18.3 mmol) and the reaction was stirred at RT for 16 h. The reaction mixture was concentrated on reduced pressure to obtain a residue which was diluted with diethyl ether and washed with water and brine solution (2*). The combined ether layer was dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford the crude product as an off-white solid, which was used in the next step without further purification (3.0 g).
The synthetic route of 22190-33-6 has been constantly updated, and we look forward to future research findings.
