Procedure

A stirred suspension of methyl 4-(allylamino)-5-amino-3-fluoro-2-(2-fluoro-4-iodophenylamino)benzoate (3.4 g, 7.4 mmoles)) and formamide acetate (3.8 g, 36.4 mmoles) in methanol (30 ml) is heated under reflux for 3 hours. The reaction mixture is cooled to room temperature and a saturated aqueous solution of sodium bicarbonate (30 ml) and water (30 ml) are added. The resulting precipitate is filtered and dried under vacuum to obtain the title compound.
