To a solution of di-tert-butyl (4-{(3R,4S,5S)-4-azido-3-[(tert-butoxycarbonyl)amino]-5-methylpiperidin-1-yl}pyridin-3-yl)imidodicarbonate (1.337 g, 2.441 mmol) in THF (20 mL), water (1.00 mL, 55.5 mmol) was added, followed by trimethylphosphine (383 mg, 5.03 mmol). The mixture was stirred at 50° C. for 15 h. The mixture was then concentrated under reduced pressure. The residue was diluted with EtOAc, washed with brine, dried over Na2SO4, filtered, and concentrated under reduced pressure to give the sub-title compound as a white foamy solid (1.336 g, 105%). LCMS calc. for C26H44N5O6 (M+H)+: m/z=522.3. Found: 522.3.
