73918-56-6, name is 2-(4-Bromophenyl)ethanamine, belongs to bromides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. 73918-56-6

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¡Á2), 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%).

Statistics shows that 73918-56-6 is playing an increasingly important role. we look forward to future research findings about 2-(4-Bromophenyl)ethanamine.
