Procedure
Sodium azide (0.31 g, 4.79 mmol) was added to a solution of 68a) (0.75 g, 1.37 mmol) in DMF (8.65 mL) and the resulting mixture was stirred at 60° C. for 2 h. After cooling to ambient temperature, the reaction mixture was poured onto water and extracted with dichloromethane (3×30 mL). The organic phase was dried over sodium sulfate and concentrated. The remnant was purified by flash column chromatography [silica; 2.5% methanol in dichloromethane]. White solid. Yield: 0.4 g (59% of theory). HPLC-MS (method 4): Rt=3.04 min; m/z [M+H]+=490.2
