To a solution of the 4-acetylphenoxy acetic acid (97 mg, 0.5 mmol) and 3-amino benzoic acid methyl ester (113 mg, 0.75 mmol) in DMF (5.0 mL) were added EDCHCl (144 mg, 0.75 mmol), HOBT (101 mg, 0.75 mmol), and DIPEA (0.13 mL, 0.75 mmol). The reaction mixture was stirred at room temperature overnight, and then partitioned between Ethyl acetate and brine. The organic phase was dried (anhydrous MgSO4), and concentrated. Purification by silica gel column chromatography (n-Hexane:Ethyl acetate:MeOH=6:3:1) gave 3-[2-(4-acetyl-phenoxy)acetylamino]-benzoic acid methyl ester as a white solid (158 mg, 97% yield).
