Procedure

A suspension of methyl 3,4-difluoro-2-(2-fluoro-4-iodophenylamino)-5-nitrobenzoate (3.9 g, 8.62 mmoles) and allylamine (3.5 ml, 43 mmoles) in a mixture of THF (10 ml), MeOH (10 ml) and H2O (2.5 ml) is stirred at room temperature for 30 min. The yellow suspension is filtered and washed with hexane to remove the excess of allylamine. The resulting solid is dried under vacuum to obtain the title compound.
