Procedure

Add 2 N sodium hydroxide solution (2 mL) to a solution of (S)-5-{5-[(3,5-bis-trifluoromethyl-benzyl)-(2-methyl-2H-tetrazol-5-yl)-amino]-7-methyl-8-trifluoromethyl-2,3,4,5-tetrahydro-benzo[b]azepin-1-ylmethyl}-2-fluoro-benzoic acid methyl ester (0.120 g, 0.167 mmol) in methanol (5 mL) and heat at 60° C. for 4 h. After the reaction cools to room temperature, acidify to pH 4 with 2 N hydrochloric acid solution and extract the aqueous mixture with ethyl acetate (3×10 mL). Wash the organic layer with water and brine (10 mL each). Dry the organic layer over anhydrous sodium sulfate, filter and remove the solvent under reduced pressure to provide the title compound as a white solid (0.116 g, 98%). 1H NMR (CDCl3, 300 MHz) δ 1.60-1.85 (m, 2H), 2.01-2.10 (m, 2H), 2.32 (s, 3H), 2.75-2.84 (m, 1H), 2.97-3.01 (m, 1H), 4.10-4.11 (m, 1H), 4.14 (s, 3H), 4.20-4.35 (m, 2H), 4.76-5.10 (m, 2H), 5.65-5.70 (m, 1H), 6.89 (s, 1H), 7.10-7.15 (m, 1H), 7.32-7.40 (m, 2H), 7.56-7.60 (m, 2H), 7.67 (s, 1H), 8.10(s, 1H); ESI MS m/z 705 [C31H26F10N6O2+H]+.
