A common compound: 73918-56-6, name is 2-(4-Bromophenyl)ethanamine, belongs to bromides-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below. 73918-56-6
To a stirring solution of 4-dimethylaminopyridine (0.19 g, 1.5 mmol) and di-tert-butyl dicarbonate (2.6 g, 12 mmol) in dichloromethane (40 mL) was added 4-bromophenethylamine (1.6 mL, 10 mmol) and stirred at room temperature for 48 hours. The reaction mixture directly adsorbed onto silica gel and purified by flash column chromatography using 0-40% ethyl acetate/hexanes as eluent to afford the title compound as a white solid (0.68 g, 22%): mp 58-59 C.; 1H NMR (400 MHz, CDCl3) delta 7.42 (d, J=8.3 Hz, 2H), 7.07 (d, J=8.3 Hz, 2H), 4.51 (s, 1H), 3.43-3.27 (m, 2H), 2.75 (t, J=7.0 Hz, 2H), 1.43 (s, 9H); 13C NMR (101 MHz, CDCl3) delta 155.79, 137.97, 131.62, 130.55, 120.25, 77.21, 41.58, 35.65, 28.39; EIMS m/z 301 ([M]+).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 73918-56-6, other downstream synthetic routes, hurry up and to see.
