A mixture of (2R,3R,4S)-5-azido-2-[(tert-butoxycarbonyl)amino]-4-cyclopropyl-3-hydroxypentyl 4-methylbenzenesulfonate (0.506 g, 1.11 mmol), DIPEA (0.31 mL, 1.8 mmol), and 10% palladium (dry basis) on activated carbon (wet, Degussa type E101 NE/W) (0.1 g) in MeOH (5 mL) was stirred under an atmosphere of hydrogen introduced via a balloon. After 3 h, the crude reaction mixture was filtered through a pad of diatomaceous earth and the solids were washed thoroughly with MeOH. The volatile organic solvents were removed under reduced pressure and the residue was dried under high vacuum to afford the sub-title compound as a solid. The crude product was used directly in the subsequent displacement reaction without further purification. LCMS (ESI) m/z calc. for C13H25N2O3 257.2 [M+H]+. found 257.2.
