Reaction Steps

To a solution of (S)-tert-butyl 5-azido-1-(tert-butoxycarbonyloxy)-4,4-difluoropentan-2-yl(methyl)carbamate (95.6 mmol) in methanol (10 mL) was added Hydrogen chloride (4.0 M in 1,4-dioxane, 240 mL, 0.596 mol). The resulting solution was stirred for overnight. The solvent was removed, and the remaining residue was dried under reduced pressure to give (S)-5-azido-4,4-difluoro-2-(methylamino)pentan-1-ol as a HCl salt, which was used without further purification. LRMS (M+H+) m/z 195.3.
