A mixture of methyl-4-(2-fluoro-4-iodo-phenylamino)-2,3-dihydro-thiophene-3-carboxylate (5.7 g, 15.0 mmol) and chloranil (5.7 g, 15.0 mmol) in toluene (50 mL) was heated to reflux for 2 hours. The solution was cooled to room temperature and the solvent was evaporated. The resulting dark brown solid was recrystallized from methanol to provide methyl 4-(2-fluoro-4-iodo-phenylamino)-thiophene-3-carboxylate (2.8 g, 49.5% yield). MS (EI) for C12H9FINO2S: 378 (MH+).
