実験手順

To a mixture of 2-amino-5-nitro-benzoic acid (12.9 g, 81.9 mmol), 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (EDCl) (17.3 g, 90.1 mmol), 1-hydroxybenzotriazole hydrate (HOBt) (12.2 g, 90.1 mmol) in THF (200 mL) was added 4-methylmorpholine (NMM) (9.91 mL, 90.1 mmol). After 10 minutes, ammonium hydroxide (50% v/v, 50 mL) was added. The mixture was stirred at room temperature under nitrogen for 17 hours. Solvent was removed under reduced pressure. Water was added. The solid separated was filtered, washed with aqueous NaHCO3 solution, and with water, and dried in air, to afford 2-amino-5-nitro-benzamide as a yellow solid. Yield: 9.88 g (66%).
