A slurry of Compound 3 (950 mg) and sodium azide (255 mg) in dry N,N-dimethylformamide (10 mL) was heated at 70° C. for 3 hours under argon. The N,N-dimethylformamide was removed from the reaction mixture under vacuum and directly eluted on a silica gel using 2% ethanol in dichloromethane to afford the required product in 83% yield (800 mg).
