To a solution of 4-amino-3-iodo-5-nitro-benzoic acid methyl ester in ethyl acetate (50 mL) was added SnCl2 dihydrate. The mixture was heated to 70° C. for two hours, then cooled to room temperature and partitioned between ethyl acetate and satruated aqueous sodium bicarbonate. The organic layer was separated, dried over MgSO4, filtered and concentrated under reduced pressure to provide 1.68 g (quantitative) of 3,4-diamino-5-iodo-benzoic acid methyl ester.
