A solution of 1.0 g (4.9 mmol) of methyl 2-amino-3-hydroxybenzoate 9a, 1.03 g (7.4 mmol) of 4-fluorobenzoic acid 9b, 10 mL DMF and 2.9 mL (20.6 mmol) of TEA were placed into a flask and stirred for 10 min. HATU (7.4 mmol, 2.8 g) was added and the reaction was stirred overnight. The reaction mixture was poured into water and extracted with EtOAc. The organics were washed with water and brine and the solvent was evaporated to give 1.2 g of crude product, methyl 2-(4-fluoro-benzoylamino)-3-hydroxy-benzoate, 9c, which was used without purification. MS m/z (M+H+) 290.1.
