Procedure

To Intermediate 5A (47 g, 17.3 mmol) in AcOH (470 mL) was added NaN3 (33.76 g, 51.9 mmol) and trimethyl orthoformate (56.8 mL, 51.9 mmol). After 30 h, the reaction was poured into ice H2O, the solids were filtered-off and washed with petroleum ether to afford 49 g Intermediate 5B. MS (ESI) m/z: 324.8 (M+H)+.

Workup
