Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 22190-33-6, name is 5-Bromoindoline, This compound has unique chemical properties. The synthetic route is as follows., COA of Formula: C8H8BrN
A solution of 5-bromo-2,3-dihydro-1H-indole (4.97 g, 25.1 mmol), di-tert-butyl dicarbonate (6.0 g, 27.5 mmol) and 4-dimethylaminopyridine (catalytic) in dichloromethane (70 mL) was stirred at room temperature until the starting material was consumed. The solvent was evaporated in vacuo, and the residue was purified by flash chromatography on silica gel, eluted with ethyl acetate/hexane to give the product, 4.1 g (55%). 1H NMR (CDCI3) : delta 1.55 (s, 9 H), 3.06 (t, 2 H), 3.97 (t, 2 H), 7.23-7.27 (m, 2 H) and 7.72 (br m, 1 H).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 22190-33-6.
