Adding a certain compound to certain chemical reactions, such as: 58971-11-2, name is 3-Bromophenethylamine, belongs to bromides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 58971-11-2, Quality Control of 3-Bromophenethylamine
General procedure: Toa solution of 2a (20.0 g, 0.1 mol)and triethylamine (30.3 g, 0.3 mol) in DCM (350 mL) was added ethylchloroformate (12.9 g, 0.1 mol) dropwise at 0 oC and then stirred atroom temperature for 3 h. The reaction mixture was washed with 3M HCl (100 mL×2), dried over Na2SO4 and concentrated under reducedpressure. The residue was purified by silica gel column chromatography (PET/EA= 25:1, v/v) to afford compound 3a as colorless oil (22.3 g, 82.0%).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3-Bromophenethylamine, and friends who are interested can also refer to it.
