Reaction Steps
A solution of N-methylisatoic anhydride (5 g, 28 mmol) in THF (100 mL) was treated with methylamine (THF solution, 2.0 M, 60 mL). The mixture was stirred for 18 h and the solvent was evaporated. The residue was partitioned between ethyl acetate (100 ml) and water (50 ml). The organic layer was washed once with brine (30 ml), dried over sodium sulfate, and concentrated to give N-methyl-2-methylamino-benzamide (5 g, 30 mmol): 1H NMR (300 MHz, CDCl3): δ 7.3 (m, 2H), 6.67 (d, 1H), 6.58 (t, 1H), 2.96 (d, 3H), 2.86 (d, 3H); MS (m/e) 165 (M+1).
