실험 절차

(2S)-(2-Amino-5-chloro-benzoylamino)-3-biphenyl-4-yl-propionic acid methyl ester was prepared following General Procedure A using 2-amino-5-chloro-benzoic acid (1.751 g, 98%, 10 mmol), (S)-2-amino-3-(4-bromo-phenyl)-propionic acid methyl ester hydrochloride salt (2.95 g, 10 mmol), HBTU (4.55 g, 12 mmol) and DIEA (6.33 mL, 99%, 36 mmol) in DMF (60 mL). Purification by flash chromatography (ethyl acetate/hexanes 1:3, 1:2, 1:1.5) gave solid (3.48 g, 8.45 mmol, 85% yield).
