反応手順

To a stirred solution of 2-amino-6-methoxy-benzoic acid (3.00 g, 17.9 mmol) in THF (90 mL), EDCl (7.89 g, 41.1 mmol) and HOBt (7.95 g, 51.9 mmol) were added and stirred at room temperature for 30 minutes then N-methylmorpholine (6.15 g, 60.0 mmol) and aqueous 50% v/v NH4OH (12 mL, 171.4 mmol) was added. The mixture was stirred for 16 hours at room temperature. The solvent was removed under reduced pressure and the residue was extracted with ethylacetate (4×100 mL), the combined organic phase was washed with water and brine, and dried over anhydrous sodium sulfate; the solvent was evaporated to give 2-amino-6-methoxy-benzamide as an off-white solid. Yield: 1.90 g, (65%).
