실험 절차

(3,5-Bis-trifluoromethyl-benzyl)-(5′-isopropyl-2′-methoxy-4-trifluoromethyl-biphenyl-2-ylmethyl)-(2H-tetrazol-5-yl)-amine (400 mg) is dissolved in N,N-dimethylformamide (3 ml) and thereto are added triethylamine (2 ml) and ethyl 4-bromobutyrate (278 μl) and the mixture is stirred at 50° C. for 3 hours. To reaction mixture is added water, and extracted with ethyl acetate, and the organic layer is washed with a saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The resulting residue is purified by silica gel column chromatography (hexane:ethyl acetate=10:1) to give ethyl 4-{5-[(3,5-bis-trifluoromethyl-benzyl)-(5′-isopropyl-2′-methoxy-4-trifluoromethyl-biphenyl-2-ylmethyl)-amino]-tetrazol-2-yl}-butyrate (360 mg) MS (m/z): 732 [M+H]+
