Reaction Steps

To a solution of (S)-(3,5-Bis-trifluoromethyl-benzyl)-(7-methyl-1-piperidin-4-ylmethyl-8-trifluoromethyl-2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-yl)-(2-methyl-2H-tetrazol-5-yl)-amine (Example 120) (0.18 mmol) in DMF (3 mL), add bromo-acetic acid ethyl ester (0.54 mmol) and cesium carbonate (0.90 mmol). After heating the mixture at 50° C. for 30 minutes, cool to room temperature and dilute the reaction with water (15 mL) and extract with ethyl acetate (3×10 mL). Dry the combined organic phases over sodium sulfate, filter, and remove solvent under vacuum. Chromatograph the product over silica gel, eluting with ethyl acetate/hexane (5-50%), to give the title compound as a colorless foam. MS (ES+): 736 (M+H).
