Reaction Steps
The product from Example 297A (4.00 g, 19.4 mmol) in acetone (9 mL) at 0° C. ws treated with sodium azide (1.27 g) in water (9 mL) dropwise over 15 minutes. after stirring for 30 minutes at 0° C., the mixture was extracted with toluene (20 mL). The toluene solution was dried over MgSO4, filtered, and the filtrate was heated to reflux for 1 hour. The cooled solution was concentrated under reduced pressure to provide the title compound.
