실험 절차

4.0 g (18.7 mmol) of methyl 2-amino-5-fluoro-4-nitro-benzoate were dissolved in 250 ml of methanol and saturated with ammonia at -40° C. Subsequently, the mixture was stirred at room temperature overnight. The solution was concentrated and ther residue was triturated with methylene chloride. The precipitate was filtered off under suction and dried. 3.17 g (85%) of 2-amino-5-fluoro-4-nitro-benzamide were obtained as yellow crystals;
