Reaction Steps
Next, (S)-2-((S)-2-(3′-chloro-biphenyl-4-yl)-1-{[1-(4-methoxy-benzyl)-1H-tetrazol-5-yl]-methyl-carbamoyl}-ethylamino)-propionic acid ethyl ester (260 mg, 0.451 mmol) was dissolved in TFA (5 mL) and DCM (5 mL) and stirred at 50° C. for 12 hours and at 75° C. for 5 hours. The reaction mixture was concentrated under reduced pressure to give (S)-2-{(S)-2-(3′-chloro-biphenyl-4-yl)-1-[methyl-(1H-tetrazol-5-yl)-carbamoyl]-ethylamino}-propionic acid ethyl ester (120 mg). MS: m/z (MH+) 457; HPLC retention time 0.95 min (HPLC condition C).
