Reaktionsschritte
A solution of 2-(dimethylphosphonomethylamino)-3-(4-biphenylyl)-propionic acid (2.27 g, 6.25 mmol), β-alanine t-butyl ester hydrochloride (1.36 g, 7.5 mmol), hydroxybenzotriazole (1.05 g, 6.85 mmol), triethylamine (2.41 mL, 17.3 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC, 1.6 g, 8.22 mmol) in dimethylformamide (60 mL) is stirred for 3 hours at room temperature, then diluted with ethyl acetate, washed with ice water, dried (Na2SO4) and chromatographed on silica gel [CH2Cl2 :MeOH:hexanes/76:4:20] to obtain t-butyl N-[2-(dimethylphosphonomethylamino)-3-(4-biphenylyl)-propionyl]-3-aminopropionate.
