Procedure
To a solution of (S)-4-{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}-piperidine-1-carboxylic acid tert-butyl ester (0.09) in dichloromethane (10 mL), add trifluoroacetic acid (2 mL). After stirring for 1 h at room temperature, quench the reaction with concentrated sodium carbonate (10 mL) and dilute with dichloromethane (20 mL) and water (20 mL). Separate the organics and wash the aqueous with dichloromethane (2×10 mL). Dry the combined organics over sodium sulfate, filter, and remove solvent under vacuum. Chromatograph the reaction over silica gel eluting with methanol/dichloromethane (0-5%) to afford the title compound as a colorless foam. MS (ES+): 650 (M+H).
