Participants

Reaction Steps

To a solution of (S)-(3,5-Bis-trifluoromethyl-benzyl)-(2-methyl-2H-tetrazol-5-yl)-(7-methyl-8-trifluoromethyl-2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-yl)-amine (Example 3, Step 18) (0.09 mmol) in dimethylformamide (3 mL), add bromoacetonitrile (0.36 mmol) and cesium carbonate (0.36 mmol). After stirring the reaction at 60° C. for 6 h, cool to room temperature and dilute with water (20 mL) and ethyl acetate (30 mL). Separate the organic phase and wash the aqueous with ethyl acetate (2×10 mL). Dry the combined organics over sodium sulfate, filter, and remove solvent under vacuum. Chromatograph the product over silica gel, eluting with ethyl acetate/hexane (5-40%), to afford the title compound as a colorless foam. MS (ES+): 592 (M+H).
