Reaction Steps

4-{5-[(3,5-Bis-trifluoromethyl-benzyl)-(5′-isopropyl-2′-methoxy-4-trifluoromethyl-biphenyl-2-ylmethyl)-amino]-tetrazol-2-yl}-butyric acid (154 mg) is dissolved in ethanol (3 ml), and thereto is added 1M-aqueous sodium hydroxide solution (225 μl), and concentrated under reduced pressure to give 4-{5-[(3,5-bis-trifluoromethyl-benzyl)-(5′-isopropyl-2′-methoxy-4-trifluoromethyl-biphenyl-2-ylmethyl)-amino]-tetrazol-2-yl}-butyric acid sodium salt (153 mg). MS (m/z): 702 [M−Na]+
