実験手順: To 11.0 g (0.0464 mole) of benzyl N-[1-(hydroxymethyl)-2-methyl-propyl]carbamate in dioxane (100 mL) cooled to 0° C. was added diphenylphosphoryl azide 10.99 mL (1.1 eq) followed by the addition of DBU 8.32 mL (1.2 eq). The contents were allowed to warm to room temperature and stirred for 16 hrs. After the addition of ethyl acetate (300 mL) and water (100 mL), the organic layer was separated and then washed with satd. NaHCO3 (100 mL). The organic layer was then dried (magnesium sulfate) and then concentrated under vacuum. To this intermediate in DMSO (100 mL) was added sodium azide 7.54 g and the contents then heated to 90 degrees for 2 hrs. After addition of ethyl acetate and water the layers were separated. The organic layer was dried with magnesium sulfate followed by concentration under vacuum to afford an oil that was columned using hexane/ethyl acetate (0-70%) to afford benzyl N-[1-(azidomethyl)-2-methyl-propyl]carbamate 6.9 g as a colorless oil. the organic layer was separated washed with satd The organic layer was then dried (magnesium sulfate) concentrated under vacuum To this intermediate in DMSO (100 mL) was added sodium azide 7.54 g the contents then heated to 90 degrees for 2 hrs After addition of ethyl acetate and water the layers were separated The organic layer was dried with magnesium sulfate followed by concentration under vacuum to afford an oil that
