Reaction Steps

To a solution of the 4-biphenyl acetic acid (106.1 mg, 0.50 mmol), 3-amino benzoic acid methyl ester (113.4 mg, 0.75 mmol), EDCHCl (143.8 mg, 0.75 mmol) and HOBT (101.4 mg, 0.75 mmol) were dissolved in DMF (5.0 mL), and DIPEA (0.13 mL, 0.75 mmol) were added. 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-biphenyl-4-yl-acetyl-amino)benzoic acid methyl ester as a white solid (174 mg, 100% yield).
