実験手順

To a dimethyl sulfoxide (100 mL) solution of intermediate (11c) (15 g, 20 mmol) was added sodium azide (3.9 g, 60 mmol). The mixture was stirred at room temperature for 20 minutes. EtOAc (500 mL) and saturated aqueous NaCl (100 mL) were added and the layers were separated, retaining the organic layer. The organic was washed an additional three times with saturated aqueous NaCl (100 mL). After drying over sodium sulfate and filtration, the removal of solvent provided intermediate (11d) as a yellow solid (12 g), which was used directly in the next step. MS m/z: [M+H+] calcd for C41H36ClN9, 690.29; found 690.5.
