How is 2-(2-Bromophenyl)acetaldehyde (CAS: 96557-30-1) typically synthesized?

2-(2-Bromophenyl)acetaldehyde can be synthesized through the bromination of acetophenone followed by hydrolysis. The bromination step is typically performed using N-bromosuccinimide (NBS) as the brominating agent. The reaction mixture is then hydrolyzed with aqueous acid to produce the desired aldehyde. The yield is around 70-80%, and the reaction requires careful control of temperature and reagents to achieve high selectivity.
