Versuchsvorschrift

To a solution of (3R,4R,5S)-1-{3-[bis(tert-butoxycarbonyl)amino]pyridin-4-yl}-3-[(tert-butoxycarbonyl)amino]-5-methylpiperidin-4-yl methanesulfonate (0.57 g, 0.96 mmol) in DMF (5.0 mL), sodium azide (0.31 g, 4.8 mmol) was added. The reaction mixture was heated at 90° C. for 5 h then allowed to cool. The solution was then partitioned between EtOAc and water. The layers were separated organic layer was washed with aq. Na2CO3 and brine, then dried, filtered and concentrated under reduced pressure to give the sub-title compound (0.52 g, 99%). LCMS calc. for C26H42N7O6 (M+H)+: m/z=548.3. Found: 548.4.
