4-Fluoro-5-((2-fluorophenyl)amino)benzo[d]oxazole-6-carboxylic acid can be reacted with halogenations reagent (such as NIS) under acidic condition in appropriate solvent. The reaction generally is carried out at ambient temperature and normally completes within several hours (1-12 h, prefer 3-10 h). 4-Fluoro-5-((2-fluoro-4-iodophenyl)amino)benzo[d]oxazole-6-carboxylic acid is obtained after conventional workup.
