Reaction Steps

A mixture of diethyl 4-aminobenzylphosphonate (36 mg), 3-[5-(3-chloro-4-fluorophenyl)-4-isoxazolyl]propionic acid (27 g), 1-hydroxy-7-aza-1H-1,2,3-benzotriazole (20 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (30 mg) and N,N-dimethylformamide (0.5 ml) was stirred at room temperature overnight. The reaction mixture was poured into 1N aqueous hydrochloric acid solution and the mixture was extracted with ethyl acetate. The ethyl acetate layer was concentrated, and the obtained solid was purified by preparative HPLC to give 3-[5-(3-chloro-4-fluorophenyl)-4-isoxazolyl]-N-[4-(diethylphosphonomethyl)phenyl]propionamide.
