Reaction Steps

To a solution of (S)-{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-yl}-acetonitrile (0.1 mmol) in toluene (6 mL), add azidotributyltin (0.1 mmol) and heat at 100° C. After heating for 14 h, cool to room temperature and dilute with ethyl acetate (20 mL). Wash the reaction with concentrated sodium fluoride (2×20 mL), dry the organic phase over sodium sulfate, filter, and remove solvent under vacuum. Chromatograph the product over silica gel, eluting with methanol/dichloromethane (0.5-5%), to afford the title compound as a colorless foam. MS (ES+): 633 (M+H).
