Reaction Steps

To a solution of (S)-(4-{5-[(3-Chloro-5-trifluoromethyl-benzyl)-(2-methyl-2H-tetrazol-5-yl)-amino]-7,9-dimethyl-8-trifluoromethyl-2,3,4,5-tetrahydro-benzo[b]azepin-1-ylmethyl}-cyclohexyl)-acetic acid methyl ester (0.1 mmol) in methanol (1 mL), add 4N sodium hydroxide (0.5 mL). Heat the mixture at 60° C. for 3 h. Dilute the cooled mixture with water and 1N HCl to bring the pH to 6-7 and extract with CH2Cl2 (3×15 mL). Combine the organic layers, dry over sodium sulfate, filter, and concentrate under reduced pressure to give a residue. Purify the residue by chromatography (elution with 5%-10% methanol in EtOAc) to afford the title compound. MS (ES+): 687 (M+H).
