Procedure

Compound 159 (3.01 g, 7.05 mmol), sodium azide (1.26 g, 19.40 mmol) and DMSO (12 mL) were combined and heated to 60° C. for 3 hours. EtOAc (100 mL) was added to the reaction and filtered. The solids were washed with EtOAc (20 mL), and the filtrated evaporated. The crude material was chromatographed on silica eluting with 5% EtOAc/hexanes to give 160 as an oil (1.86 g, 89%).
