Reaction Steps

To a suspension of 16.3 g (100 mmol) of isatoic anhydride in 100 mL of H2O is added portionwise 100 mL of 2N methylamine-tetrahydrofuran solution (200 mmol) at room temperature. The reaction mixture is stirred for 1 hour and then extracted with AcOEt. The organic layer is washed with H2O and brine, dried over Na2SO4, and concentrated under reduced pressure to give 13.79 g of desired product, 2-amino-N-methyl-benzamide (92 mmol, 92%) as colorless solid.
