Reaction Steps

To a solution of (S)-9-[(3,5-bis-trifluoromethyl-benzyl)-cyano-amino]-1,3,6,7,8,9-hexahydro-2-oxa-5-aza-cyclohepta[f]indene-5-carboxylic acid tert-butyl ester (1.61 mmol) in toluene (10 mL), add azidotributyltin (3.22 mmol) and heat to 100° C. After stirring for 12 h, cool the reaction to room temperature and quench with methanol (1 mL). Dilute the reaction mixture with ethyl acetate (100 mL) and wash with aqueous sodium fluoride (50 mL) and brine (50 mL). Dry the organic portion over sodium sulfate, filter, and remove the solvent under vacuum. Chromatograph the product over silica gel, eluting with methanol/dichloromethane (1-5%) to afford the title compound as a colorless foam. MS (ES+): 597.3 (M−H).
