A solution of 2-amino-3,5-dimethyl-benzoic acid (550 mg) in DCM (30 mL) was treated with HOBt (225 mg), EDC (1280 mg), and CH3NH2 (8.5 mL, 2N in THF). The reaction mixture was stirred for 16 hours in a sealed bottle, diluted with DCM (100 mL), and washed with brine three times. The organic layer was dried (sodium sulfate), and concentrated in vacuo. The residue was purified by silica gel chromatography to provide 573 mg of 2-amino-3,5-dimethyl-benzamide: 1H NMR (300 MHz, CDCl3) δ 7.9 (s, 1H), 7.8 (s, 1H), 6.1 (bs, 1H), 5.3 (bs, 2H), 2.9 (d, 3H), 2.2 (s, 3H), 2.1 (s, 3H).
