実験手順

25.8 g (93.8 mmol) of methyl 2-amino-5-bromo-4-nitro-benzoate were dissolved in 800 ml of methanol and saturated with ammonia at -40° C. Subsequently, the mixture was stirred at room temperature overnight. The solution was concentrated and the residue was triturated with methylene chloride. The precipitate was filtered off under suction and dried. 18.3 g (75%) of 2-amino-5-bromo-4-nitro-benzamide were obtained as orange coloured crystals;
