摘要:
A process for producing 2,3,4-trifluoro-5-(iodo or bromo)benzoic acid, the process comprising a haloganation step in which 2,3,4-trifluorobenzoic acid is iodinated or brominated directly with an iodinating agent or brominating agent in a reaction solvent in the presence of an oxidizing agent. This process can produce 2,3,4-trifluoro-5-(iodo or bromo)benzoic acid in a simple manner in high yield, at high purity and with high stereoselectivity.
