Electric Literature of 96558-78-0, The chemical industry reduces the impact on the environment during synthesis 96558-78-0, name is 3-Bromo-5-chlorophenylamine, I believe this compound will play a more active role in future production and life.
Preparation of starting material 3-chloro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (SM-17) This material was prepared from 3-bromo-5-chloroaniline following a similar procedure used for SM-9, step 3. The crude product was purified by flash chromatography (RediSep Cyano, Teledyne ISCO, 0-50% EtOAc in hexanes) to afford 3-chloro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (48%) as a pale orange solid: LCMS(m/z) 172.1 (MH+), tR=0.33 minute.
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, 3-Bromo-5-chlorophenylamine, other downstream synthetic routes, hurry up and to see.
