Participants

Reaction Steps

To a solution of 500 mg (3.0 mmol) of methyl 2,3-diaminobenzoate 9w and 730 mg (6.0 mmol) of benzoic acid 9x in 8 mL of CH2Cl2 was added 620 mg (3.0 mmol) of dicyclohexylcarbodiimide (DCC) and 4 mg (0.033 mmol) of DMAP. The reaction was stirred overnight and the solid was filtered off. The solid was purified by flash column chromoatography (silica gel, 10-30% gradient of EtOAc in heptanes) to give 220 mg (27%) of methyl 3-Amino-2-benzoylamino-benzoate, 9y. MS m/z (M+H+) 271.2
