Reaction Steps

Add aqueous 5 M NaOH (2.4 mL, 12 mmol) to a solution of (S)-9-[(3,5-Bis-trifluoromethyl-benzyl)-(2-methyl-2H-tetrazol-5-yl)-amino]-2,3,6,7,8,9-hexahydro-1H-5-aza-cyclohepta[f]indene-5-carboxylic acid 2-methoxycarbonyl-2-methyl-propyl ester (86 mg, 0.13 mmol) in methanol (3.4 mL). Heat the mixture at 60° C. for 1 h. Cool down to room temperature. Dilute with water and neutralize with 2 M HCl. Extract aqueous phase with ethyl acetate. Dry organic layers with anhydrous sodium sulphate and evaporate the solvent. Purify the residue by chromatography (elution with dichloromethane/methanol) to afford the title compound (62 mg, 73%). MS (ES+): 655 (M+H).
