Abstract
A new synthetic method was introduced of 2-Amino-3,5-dibromobenzaldehyde.It was synthesized from o-nitrobenzaldehyde,Iron powder for reducing agent,acetic acid and ethanol as solvent,obtained o-amino benzaldehyde(Ⅰ).And then bromination by NBS.The overall yield of target product was 84.3%.The product was characterized by 1H NMR spectrometry.The method is easy to operate and high safety.
