4-Fluoro-5-((2-fluoro-4-iodophenyl)amino)benzo[d]oxazole-6-carboxylic acid can be reacted with O-(2-(vinyloxy)ethyl)hydroxylamine in the presence of coupling reagent in appropriate solvent. The reaction is generally carried out at ambient temperature and normally complete within several hours (1-12 h, prefer 3-10 h). 4-Fluoro-5-((2-fluoro-4-iodophenyl)amino)-N-(2-(vinyloxy)ethoxy)benzo[d]oxazole-6-carboxamide is obtained after conventional workup.
