In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 22190-33-6 as follows. Computed Properties of C8H8BrN
To a solution of 5-bromo-2,3-dihydro-1H-indole (2.11 g, 10.7 mmol) in 40 mL of THF was added Boc2O (2.56 g, 11.7 mmol). The reaction mixture was stirred at room temperature for 18 hours, and then concentrated under reduced pressure. Purification of the residue via flash chromatography (8% EtOAc in hexane) afforded 5-bromo-2,3-dihydro-indole-1-carboxylic acid tert-butyl ester (2.59 g, 95%) as a white solid; MS (M+H)=298.
According to the analysis of related databases, 22190-33-6, the application of this compound in the production field has become more and more popular.
