실험 절차

(S)-2-[(S)-2-(3′-chloro-biphenyl-4-yl)-1-(1H-tetrazol-5-ylcarbamoyl)-ethylamino]-propionic acid ethyl ester (100 mg, 0.226 mmol) was treated with 2M aqueous NaOH (2 mL) and EtOH (0.5 mL). After stirred at room temperature for 1 hour, the reaction mixture was acidified with 2M HCl to adjust pH 1. The resulted precipitate was collected by filtration. The obtained material was crystallized from EtOH to give (S)-2-[(S)-2-(3′-chloro-biphenyl-4-yl)-1-(1H-tetrazol-5-ylcarbamoyl)-ethylamino]-propionic acid (94 mg).
